what is the equation to find the equivalent resistance, req, of two resistors in series, r1 and r2? group of answer choices

Answers

The equivalent resistance of resistors in series is always greater than the individual resistances. This is because the total resistance of the circuit is the sum of the resistances, and therefore the electric current has to overcome more resistance to flow through the circuit as compared to when a single resistor is used.

To find the equivalent resistance, req, of two resistors in series, r1 and r2, the following equation is used:

Req = R1 + R2

Where Req is the equivalent resistance of the series circuit,

R1 is the resistance of the first resistor,

R2 is the resistance of the second resistor.

Resistors in a circuit are the components that oppose the flow of electric current. When two resistors are connected in series, they are connected end to end so that the electric current flows through one resistor before flowing through the second one.In a series circuit, the equivalent resistance, req, is calculated as the sum of the individual resistances of the resistors connected in series.

Therefore, to find the equivalent resistance of two resistors in series, R1 and R2, we add the resistance values of the two resistors, as shown in the formula above.

which has a greater (magnitude of) linear momentum: a 1000 kg truck moving at 30 mph, or a 500 kg car moving at 60 mph?

Answers

Answer : A 1000 kg truck moving at 30 mph has a greater magnitude of linear momentum than a 500 kg car moving at 60 mph, due to the larger mass of the truck and the lower velocity of the truck.

The magnitude of linear momentum for an object is equal to the product of its mass and velocity. Therefore, a 1000 kg truck moving at 30 mph has a linear momentum of 30,000 kg-m/s, while a 500 kg car moving at 60 mph has a linear momentum of 30,000 kg-m/s as well. As the magnitudes of linear momentum for both the truck and car are equal, the truck has a greater linear momentum than the car.

This is because the truck has a larger mass than the car and is moving at a lower velocity. In other words, the higher mass of the truck counteracts its lower velocity, resulting in an overall greater linear momentum. This can be illustrated with the equation p = mv, where p is linear momentum, m is mass, and v is velocity.

a 4.0 kg body has two times the kinetic energy of an 8.5 kg body. calculate the ratio of the speeds of these bodies.

Answers

The ratio of the speeds of these bodies is 2.06

The kinetic energy of an object is equal to 1/2mv^2.
For the 4.0 kg body, the kinetic energy is 1/2 (4.0 kg)v^2
For the 8.5 kg body, the kinetic energy is 1/2 (8.5 kg)u^2

Given that the kinetic energy of the 4.0 kg body is twice the kinetic energy of the 8.5 kg body, we can set up the following equation:

1/2 (4.0 kg)v^2 = 2 * (1/2 (8.5 kg)u^2)

Simplifying the equation, we have:

2 (4.0 kg)v^2 = (8.5 kg)u^2

Solving for the ratio of the speeds, we get:

v^2/u^2 = (8.5 kg)/(2 (4.0 kg)) = 4.25

Therefore, the ratio of the speeds of the two bodies is equal to the square root of 4.25, which is approximately equal to 2.06.

So, the 4.0 kg body is moving at approximately 2.06 times the speed of the 8.5 kg body.

how long must a 0.70- mm -diameter aluminum wire be to have a 0.42 a current when connected to the terminals of a 1.5 v flashlight battery?

Answers

To determine the length of an aluminum wire required to carry a certain current, one must use the formula: r = (ρL) / (πr²), where r is the radius of the wire, ρ is the resistivity of the wire, and L is the length of the wire is 48.54 m.

What is the length of the wire?

A 0.70 mm diameter aluminum wire has a radius of 0.35 mm or 0.00035 m. The resistivity of aluminum is 2.82 × 10⁻⁸Ωm. The formula for current is:

I = V / R

where, V is voltage, and R is resistance. We can rearrange this to:

R = V / I

Plugging in the given values of 0.42 A and 1.5 V gives R = 3.571 Ω. The resistance of a wire is given by:

R = ρL / A

where, A is the cross-sectional area of the wire, and ρ is its resistivity.

We know the resistivity of aluminum and the radius of the wire, so we can calculate the cross-sectional area of the wire:

A = πr² = 3.1416 × (0.00035 m)² = 3.848 x 10⁻⁷ m². Substituting all the values in the formula for the resistance of the wire and solving for L gives:

L = RA / ρ = (3.571 Ω) × (3.848 x 10⁻⁷ m²) / (2.82 × 10⁻⁸ Ωm) = 48.54 m.

Therefore, the aluminum wire must be 48.54 m long to have a current of 0.42 A when connected to the terminals of a 1.5 V flashlight battery.

discuss how errors due to earth curvature and refraction can be eliminated from the differential leveling process.

Answers



Errors due to earth curvature and refraction can be eliminated from the differential leveling process by using the trigonometric leveling method.

This method utilizes the principle of triangles to determine the height difference between two points on the Earth's surface.

The trigonometric method begins by measuring the horizontal angle between two points, then the vertical angle between the same two points, and finally the distance between the points.

The trigonometric method is not affected by the curvature of the Earth or refraction since the vertical angle is measured at a given distance instead of the line of sight.

Therefore, the measurements of the angles and distances remain unaffected.

The trigonometric leveling process is as follows: first, an instrument is set up at point A. A second instrument is then set up at point B, and both instruments are leveled.

The horizontal angle between the two points is then measured with a theodolite, followed by the vertical angle. Lastly, the distance between the two points is measured using a tape measure.

After all the measurements are taken, the results are then used in a trigonometric formula to calculate the difference in elevation between the two points.

This method eliminates errors due to refraction or the Earth's curvature, since the elevation difference is not determined by the line of sight, but rather by the measured angles and distance.

The trigonometric leveling method is the best method to eliminate errors due to the Earth's curvature and refraction from the differential leveling process.

This method uses trigonometric principles and measurements to accurately calculate the difference in elevation between two points.

g what is the relationship between the wavelength of light, its color, and the energy of its photons?

Answers

Shorter wavelengths of light correspond to higher frequencies, and higher frequencies of light correspond to more energy in the photons. This means that the color of light is related to the energy of its photons: the higher the frequency of light, the higher the energy of its photons and the closer the color is to the blue end of the visible light spectrum.

The relationship between the wavelength of light, its color, and the energy of its photons is as follows:

The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. In simpler terms, the shorter the wavelength of light, the greater the energy of its photons, while the longer the wavelength of light, the less energy its photons possess. The relationship between the wavelength of light and its color is also direct in that different colors are a result of light waves of different wavelengths.

The color spectrum ranges from red (longest wavelength) to violet (shortest wavelength), with colors in between, such as orange, yellow, green, blue, and indigo. This spectrum represents the visible part of the electromagnetic spectrum, with ultraviolet and infrared light having shorter and longer wavelengths, respectively.

Two loud speakers are 1.60 m apart. A person stands 3.00 m from one speaker and 3.50 m from other speaker.
What is the lowest frequency at which destructive interference will occur at this point if the speakers are in phase?

Answers

Answer:

f = 343 Hz

Step by step explanation:

For destructive interference to occur, the sound waves from the two speakers must be out of phase by half a wavelength. This means that the path difference between the two waves must be an odd multiple of half the wavelength.

In this case, the path difference between the two waves is given by:
Δx = d₂ - d₁
where d₂ is the distance from the second speaker to the person, and d₁ is the distance from the first speaker to the person.

Substituting the given values, we get:
Δx = 3.5 m - 3.0 m
Δx = 0.5 m

For destructive interference to occur, the path difference must be an odd multiple of half the wavelength, i.e.:
Δx = (2n + 1)λ/2
where n is an integer.

Solving for the wavelength, we get:
λ = 2Δx/(2n + 1)

The lowest frequency occurs when n is the smallest possible value, i.e. n = 0. Substituting this value, we get:
λ = 2Δx/1
λ = 2(0.5 m)
λ = 1.00 m

The frequency of the sound wave is given by:
f = c/λ
where c is the speed of sound in air (approximately 343 m/s).

Substituting the values, we get:
f = 343 m/s/1.00 m
f = 343 Hz

Therefore, the lowest frequency at which destructive interference will occur at the given point is 343 Hz.

Answers

The change in momentum of the two-object system from immediately before the collision to immediately after the collision is m(v-V) + 2m(V-v).

The change in momentum of the two-object system from immediately before the collision to immediately after the collision can be determined using the following equation:

Change in Momentum = Final Momentum - Initial Momentum.

The initial momentum of object x is given by the formula: Mass x Velocity = mv, where m is the mass of object x and v is the velocity of object x immediately before the collision. The initial momentum of object y is given by 2mv, where 2m is the mass of object y and v is the velocity of object y immediately before the collision. The final momentum of object x is given by m(v-V) where m is the mass of object x, v is the velocity of object x immediately before the collision and V is the velocity of object x immediately after the collision. The final momentum of object y is given by 2m(V-v) where 2m is the mass of object y, V is the velocity of object y immediately after the collision and v is the velocity of object y immediately before the collision. The change in momentum = m(v-V) + 2m(V-v).

No, the sound wouldn't be twice as loud as that of either flutist playing alone at that intensity. The increase in sound intensity would be less than twice as loud.

This is because when two sound waves coincide, the amplitude of the resulting sound wave is the sum of the amplitudes of the individual sound waves. That is, when two identical sound waves come together, they create a new sound wave that is slightly louder than the original sound wave, but not twice as loud.

Answers

The space station rotates in order to simulate earth's gravity so that the normal force on an astronaut at the outer edge would be the astronaut's weight on earth. The period of rotation needed to achieve this is: 29.27 minutes

The Space Station is a microgravity environment that is constantly in freefall around the Earth, but it is not affected by gravity. As a result, the astronauts in the Space Station float and move around in the Station. However, by rotating the Space Station, a simulated gravity effect can be created that is comparable to gravity on Earth.

This is due to the centrifugal force that is generated as a result of the rotation. The period of rotation required to generate the required centrifugal force can be calculated.

The centrifugal force generated by the rotation of the Space Station is equal to the force of gravity acting on the astronauts on Earth. Therefore, the formula used to calculate the period of rotation is given:
T = 2π √(R/g)

Where T is the period of rotation, R is the radius of the Space Station, and g is the acceleration due to gravity on Earth. The value of g is 9.8m/s², and the radius of the Space Station is approximately 420 kilometers.
T = 2π √(420,000 / 9.8)

Answers

Assuming that it does not slip, the acceleration of the seed is 0.89 m/s².

The acceleration of the seed can be calculated using the formula for centripetal acceleration:

a = (v²) / r

where a is the centripetal acceleration, v is the velocity of the seed, and r is the distance from the axis of rotation to the seed.

To use this formula, we need to first convert the rotational speed of the turntable from rev/min to radians per second. There are 2π radians in one revolution, so:

ω = (33 1/3 rev/min)(2π rad/rev)(1 min/60 s) = 3.49 rad/s

The velocity of the seed can be calculated from the tangential velocity formula:

v = rω

where v is the tangential velocity of the seed.

Substituting the given values, we get:

v = (0.073 m)(3.49 rad/s) = 0.255 m/s

Now we can use the formula for centripetal acceleration:

a = (v²) / r

Substituting the values we have calculated, we get:

a = (0.255 m/s)² / 0.073 m = 0.89 m/s²

Therefore, the acceleration of the seed is 0.89 m/s² assuming that it does not slip.

For the first ball (that is thrown upward from the ground), the acceleration, a = -9.8 m/s² (negative because it's going against the gravity).Using the formula of motion,S = ut + 1/2 at²where,S = height of the ball above the ground, t = time taken by the ball to reach that height, and u = initial speed of the ball that is thrown upward from the ground.

Here, h = S and u = 35 m/s, and a = -9.8 m/s². Then putting the values we get,h = ut + 1/2 at²5 = (35)t + 1/2 (-9.8)t²5 = 35t - 4.9t²----------------(1)Also, for the second ball (that is dropped from a building), the time taken to reach the ground can be found using the formula, h = 1/2gt². Here, h = 5.0 m.

Therefore,5 = 1/2 × (-9.8) × t²5 = -4.9t²t² = -5/-4.9t² = 1.02t = √1.02

Therefore, the time taken by both balls to be at the same height is 1.02 seconds.

turns people upside down. people should not drop down. this is due to: gravity. inertia. seat belts. centrifugal force.

Answers

The given statement "turns people upside down" and "people should not drop down" are both due to the centrifugal force.

What is Centrifugal Force?

Centrifugal force is defined as the apparent force that tends to move a rotating body away from the center of rotation. When an object moves in a circular path, a force must act towards the center of the circle to keep it moving in a circle. This force is known as the centripetal force.

The opposite force that acts to push the object away from the center of the circle is called centrifugal force. So, the given statement "turns people upside down" and "people should not drop down" are both due to the centrifugal force.

if the same horizontal net force were exerted on both vehicles, pushing them from rest over the same distance, what is the ratio of their final kinetic energies?

Answers

If the same horizontal net force were exerted on both vehicles, pushing them from rest over the same distance, the ratio of their final kinetic energies will be 1:1.

What Is Kinetic Energy?

The kinetic energy of an object depends on its mass and velocity, and if the force and distance traveled are the same, the velocity of the vehicles at the end of the distance will be the same. The kinetic energy of an object can be calculated using the formula: KE = 1/2mv². Where KE is the kinetic energy, m is the mass, and v is the velocity of the object. If the force and distance traveled are the same for both vehicles, their final velocities will also be the same. Therefore, the ratio of their final kinetic energies will be 1:1, regardless of the mass of the vehicles. The mass of an object only affects its kinetic energy when the force applied is not the same. In that case, the object with the larger mass will have a smaller velocity and therefore smaller kinetic energy, even if the distance traveled is the same.

Siblings who are ____ are often more extraverted and concerned with control than their brothers and sisters What is the volume of this rectangular prism?1133cmcmcm What is the purpose of this article? 1- In 1931, the American historian and writer James Truslow Adams wrote a book called "The Epic of America." Like many others, this book told the history of our nation. But unlike most history books, "The Epic of America" did not focus on events. Instead, it focused on average people. The book told the nation's history by emphasizing the ways in which the average American had changed.2- Adams stated that the American dream is "that dream of a land in which life should be better and richer and fuller for everyone." In this dream, a person's talent and dedication would determine their opportunities. This American dream was not about material possessions or money. Instead, it was a dream of a society. In this society, each man and woman could reach the highest place that their levels of talent and dedication would allow. That person would be recognized by others for what they are. Where they were born or who their family was did not matter.3- The authors of the United States Declaration of Independence believed that certain ideas were true. They believed that all men were created equal. They believed that all men were given certain rights that could not be taken away. These rights, according to the founding fathers, include the right to "life, liberty and the pursuit of happiness." Is the American dream based on this idea?The dream keeps on changing4- Consider the people of the 1850s who first settled the American West. They left the big cities of the east to find their piece of land in the unknown wilderness. Were these people following these Rights? What about the immigrants who came to the United States? Were they seeking their bit of life, liberty and the search for happiness, their dream? The soldier who returned home after World War II wished to settle down and to have a home, a car and a family. What does this desire tell us about how this dream has changed over time? Is the American dream attainable by all Americans?5- What does the freedom to pursue a better life involve to most Americans? To many, it often involves a nice house, a car or two and a more comfortable life than their parents had. A countless number of "Rags to Riches" stories have been fueled by this idea. Presidents have started out in log cabins. Highly successful entrepreneurs have come to America as penniless immigrants. Bill Gates, a man who dropped out of college, became the richest man in the world.6- Is hard work and dedication always rewarded? The American novelist Horatio Alger, Jr. wrote many stories about this idea in the 1800s. The young heroes of his books "pulled themselves up by their bootstraps" and proved America to be the land of opportunity.7- Some say that the American dream has become the search for material wealth. Today, people work more hours to get bigger cars, fancier homes and what they view as better lives for their families. As a result, they have less time to enjoy this wealth. Others say that the American dream is beyond the grasp of the working poor. What is the American dream for someone who must work multiple jobs to support their family? Yet others focus less on making more money. They place more emphasis on living a simple, fulfilling life. That is the American dream to them.8- The American novelist Thomas Wolfe said that every man, no matter where he was born, had certain rights.
