the pipe of length l that is open at both ends is resonating at its fundamental frequency. which statement about sound is correct?

Answers

Answer 1

The correct statement would be that the wavelength is 2L and there is a displacement node at the pipe's mid point, if L is the length of the open pipe.

The fundamental frequency is the smallest resonant frequency of a vibrating object. Most of the vibrating objects possess more than one resonant frequency and which are used in musical instruments. On the other hand, a harmonic is defined as an integer multiple of the fundamental frequency.

Vibrating strings, open pipe, and conical air columns vibrate at all harmonics of the fundamental. Cylinders with only one end opened vibrate with only odd harmonics of the fundamental.

Hence the correct option is A.

Answers

The final velocity of the composite object after collision is 1.8002 m/s in the direction of the first object.

Initial velocity of the first object, v₁ = 5.001 m/s

Mass of the first object, m₁ = 3.0 kg

Initial velocity of the second object, v₂ = -3.001 m/s (In opposite direction)

Mass of the second object, m₂ = 2.0 kg

Let the final velocity of the composite object, = V

Mass of the composite object, = (3.0 + 2.0) = 5.0 kg

By the law of conservation of momentum,

m₁v₁ + m₂v₂ = (m₁ + m₂) × V

V = (m₁v₁ + m₂v₂)/(m₁ + m₂)

V = (3 × 5.001 + 2 × (-3.001))/(2 + 3)

Using a balance, determine the mass of the ball and basket of the ballistic pendulum. Fire the ballistic pendulum and measure the maximum height the pendulum reaches. Use the conservation of energy (initial KE + initial GPE = final KE + final GPE, KE = 12mv2; GPE = mgh) to calculate the initial speed of the pendulum after the ball has collided with the pendulum basket. Next, use the conservation of momentum (total initial p = total final p; p = my) fo determine the initial speed of the ball before it collided with the pendulum basket. ​

Answers

The initial speed of the bullet before striking the basket of mass 1 kg is 1.98 m/s. Speed of each bullet is given below

To determine the mass of the ball and basket of the ballistic pendulum using a balance, you can simply weigh the pendulum and record its mass.

To calculate the initial speed of the pendulum after the ball has collided with the pendulum basket, you can use the conservation of energy. The initial kinetic energy (KE) of the ball is equal to the final kinetic energy of the pendulum (ball and basket combined), and the initial gravitational potential energy (GPE) of the ball is equal to the final GPE of the pendulum. The equation for KE is KE = 1/2mv^2, where m is the mass of the ball and v is its velocity. The equation for GPE is GPE = mgh, where m is the mass of the ball, g is the acceleration due to gravity (9.8 m/s^2), and h is the height of the pendulum at its maximum displacement.

Using the values for mass, height, and velocity, you can set up the conservation of energy equation as follows:

1/2mv^2 + mgh = 1/2(m + M)v_f^2 + (m + M)gh_f

where m is the mass of the ball, M is the mass of the pendulum basket, v is the initial velocity of the ball, v_f is the final velocity of the pendulum, h is the height of the pendulum at its maximum displacement, and h_f is the height of the pendulum at its maximum displacement after the collision.

Solving for v, we get:

v = sqrt(2gh)

Next, you can use the conservation of momentum to determine the initial speed of the ball before it collided with the pendulum basket. The conservation of momentum states that the total initial momentum of an isolated system is equal to the total final momentum of the system. The equation for momentum is p = mv, where m is the mass of the ball and v is its velocity.

Before the collision, the momentum of the ball is simply equal to its mass times its velocity:

p_i = mv

After the collision, the momentum of the pendulum is equal to the mass of the ball plus the mass of the pendulum basket times the final velocity of the pendulum:

p_f = (m + M)v_f

Setting the initial and final momenta equal to each other and solving for v, we get:

mv = (m + M)v_f

v = (m + M)v_f / m

So, by measuring the mass of the ball and basket, the maximum height of the pendulum, and the final velocity of the pendulum, you can use the conservation of energy and conservation of momentum to determine the initial velocity of the ball and the pendulum.

Speed of each bullet depending on the mass are:-

          m (kg)    v (m / s)

            0.05      41.58

            0.10       21.78

Answers

The instantaneous speed at the instant you turn around to move in the opposite direction is (b) always zero.

We know that the average speed for a given time interval is the total distance traveled divided by the total time taken. As this time interval approaches zero, the distance traveled also approaches zero. But the limit of the ratio of distance and time is non-zero and is called the instantaneous speed. To understand it in simple words we can also say that instantaneous speed at any given time is the magnitude of instantaneous velocity at that time.Instantaneous velocity is defined as the rate of change of position for a time interval which is very small (almost zero). Measured using SI unit m/s. Instantaneous speed is the magnitude of the instantaneous velocity. It has the same value as that of instantaneous velocity but does not have any direction.

two point charges placed 5 cm aparnt on the xa axis. at what points along the x axis is the potential zero?

Answers

The point where the potential is zero is located at [tex]x = 5 cm * k * Q1/(Q1 + Q2)[/tex]

The potential at a point in space due to a point charge is given by the equation:

V = k * Q/r

where V is the potential, k is the Coulomb constant  [tex](8.99 x 10^9 N * m^2/C^2)[/tex], Q is the charge, and r is the distance from the point charge to the point where the potential is being calculated.

In this problem, we have two point charges placed 5 cm apart on the x-axis. How about we call the charges Q1 and Q2, and we should assume that Q1 is located at the origin (x = 0) and Q2 is located at x = 5 cm.

The potential at a point along the x-axis is the amount of the potentials due to each of the point charges.

V = k * Q1/r1 + k * Q2/r2

where r1 is the distance from the point to Q1 and r2 is the distance from the point to Q2.

In the event that the potential at a point is zero, the amount of the potential due to each of the point charges is zero.

So, k * Q1/r1 + k * Q2/r2 = 0

To find the points along the x-axis where the potential is zero, we can set the equation above equal to zero and address for x.

r1 = x and r2 = |x - 5 cm|

k * Q1/x + k * Q2/|x - 5 cm| = 0

x = k * Q1/Q2 * |x - 5 cm|

x = k * Q1 * (5 cm - x)/Q2

x = 5 cm * k * Q1/(Q1 + Q2)

In this way, the point where the potential is zero is located at

x = 5 cm * k * Q1/(Q1 + Q2)

This is valid for any point in the x-axis, and these points are called equipotential points.

Any extra charge on the a conductor will be located on its surface, according to Gauss' Law.

According to Gauss' Law, the surface's electric field and internal charge are related. The charge encapsulated by any surface on the inside of a conductor equals zero since there is no electric field there. Any charge here on conductor must therefore be located on its surface. There wouldn't be an electric field inside the conductor's vicinity if a cavity was cut out of it, and there wouldn't be any charge inside the cavity either. Therefore, the hollow wouldn't have an electric field. Because of electric field should be perpendicular to its surface and the conductor's internal electric field is zero, no flux can penetrate the conductor.

Thus, on the cavity's surface there is a negative charge, while the conductor's outer surface has a positive charge.

Answers

The amount of charge that will flow from the battery is 77000pC

A capacitor is a device that stores electrical charge. The amount of charge stored in a capacitor is proportional to the voltage applied across it, according to the equation Q = C*V.

where Q is the charge in coulombs, C is the capacitance in farads, and V is the voltage in volts.

In this case, the capacitance of the air-gap capacitor is 3500pF (pico-farads) and the voltage is 22V, so the charge stored in the capacitor is:

Q = 3500pF * 22V = 77000pC (pico-coulombs)

When a piece of mica is placed between the plates, it reduces the space between the plates, which will increase the capacitance of the capacitor. The increase in capacitance will result in an increase in the amount of charge stored in the capacitor.

It's worth noting that the charge that flows from the battery is equal to the initial charge stored in the capacitor. Since the initial charge stored in the capacitor is 77000pC, this is the amount of charge that will flow from the battery.

Where θ 1 is the angle of the first line, and θ 2 is the angle of the second line.

What is angle?

Angle is the measure of a turn or displacement between two intersecting lines. Angles are typically measured in degrees, with 360 degrees in a full circle. acute angles are smaller than 90 degrees, while obtuse angles are larger than 90 degrees. Straight angles are exactly 180 degrees, while reflex angles are greater than 180 degrees.

The equation for the diffraction grating for the sodium is:
nλ = d sinθ
Where n is the order of the spectrum, λ is the wavelength of the light, d is the distance of the spectrum, and θ is the angle of the light.
For the first order, the initial angular position is:
nλ = d sinθ
θ = sin-1 (λ/d)
For the first order, the final angular position is:
nλ = d sinθ
θ = sin-1 (λ/d)
The angular separation of the two closely spaced yellow lines of sodium is:
Δθ = θ 1 - θ 2

Answers

Yes, by bringing the positively-charged object near the object to be charged, then discharging the far side.

What is positively-charged?

Positively-charged particles, or ions, are atoms or molecules that are missing one or more electrons, giving them a surplus of positive charge. This imbalance between the number of protons and electrons causes the particle to be attracted to objects with a negative charge, such as other ions.

The positively-charged object will cause electrons to be transferred to the object to be charged, thus resulting in a negative charge on the object.
Yes, by rubbing the two objects together. By rubbing the two objects together, electrons can be transferred from one object to the other, thus resulting in negative charge on one object and positive charge on the other.

a ufo going 64 m/s west suddenly experienced a constant acceleration for 63 s during which its displacement was 21,892.5 m west. determine the final speed of the ufo

Answers

The final speed of the UFO after experiencing a constant acceleration for 63 seconds is 351.3 m/s.

What is accelaration?

Acceleration is the rate at which an object increases its speed, velocity or rate of change. It is the rate of change of velocity over time, or the rate of change of the position of an object. Acceleration can be either positive, when the speed of an object is increasing, or negative, when the speed of an object is decreasing.

The final speed of the UFO can be determined by using the equation, v = u + at, where u is the initial velocity, a is the acceleration, and t is the time. So, in this case, v = 64 + (21,892.5/63) = 351.3 m/s. Therefore, the final speed of the UFO after experiencing a constant acceleration for 63 seconds is 351.3 m/s.

a ball is released from height h above the floor. the system is defined to be ball-earth. air resistance is negligible. when the ball is halfway to the ground (i.e. at height h/2), is its kinetic energy more than, less than, or equal to half of its maximum kinetic energy?

Answers

When the ball is halfway to the ground (i.e. at height h/2), is its kinetic energy is more than, its maximum kinetic energy.

Air exerts a force known as air resistance. Like a sports vehicle with a streamlined design will encounter reduced air resistance and experience less drag, the automobile would be able to move more quickly than a truck with a flat front.

Air resistance is what generates this force. The force of air resistance slows an object's descent to the ground more as its mass decreases. Regardless of how much their masses differ, if two items were put on the moon, where there is no air, they would fall at the same rate.

A new planet is discovered orbiting a star with a mass 3. 5 × 10^31 kg at a distance of 1. 2x10^11 m. Assume that the orbit is circular. What is the gravitational acceleration on this new planet?​

Answers

The gravitational acceleration of this new planet is [tex]24.3 * 10^{9} G m/s^{2}[/tex].

Any object located in the field of the planet experiences a gravitational pull. Gravitational acceleration is described as the object receiving an acceleration due to the force of gravity acting on it. It is represented by ‘g’ and its unit is m/s2. Gravitational acceleration is a quantity of vector, that is it has both magnitude and direction.Using the following equation, the gravitational acceleration acting on anybody can be explained. When the object is on or near the surface of the body, the force of gravity acting on the object is almost constant and the following equation can be used:

                                        g = GM/R^2

Here,

G = the universal gravitational constant (G = gravitational constant of planet)

M = Mass of planet = [tex]3.5*10^{31} kg[/tex]

R = Radius = 1.2*10^11 m

a car drives straight off a flat cliff that is 57 m high (its initial velocity is purely horizontal). the point of impact is 130 m from the base of the cliff. how fast was the car traveling when it went over the cliff?

Answers

The speed of the car traveling when it went over the cliff is 38.12 m/s.

The equation of motion for calculating the displacement of a moving object is given as

                                           [tex]S = ut + \frac{1}{2} at^{2}[/tex]

u = initial velocity

t = time taken

a = acceleration of the object

S = displacement of the object

The above equation can be used to find out the speed of the car.

In this case, the initial velocity, u, is zero because the car falls under gravity. The acceleration, a, will be considered as acceleration due to gravity (g). The time taken is the 'time of flight' taken as 't' and S is taken as the height (h) of the flat cliff.

        Therefore, the above equation can be written as

                                               [tex]h = \frac{1}{2} gt^{2}\\t = \sqrt[]{\frac{2h}{g} } \\t = \sqrt[]{\frac{2(57)}{9.8} } \\\\t = 3.41 s[/tex]

Therefore, the time of flight = 3.41 s.

If the point of impact from the base of the cliff is 130 m and the time of flight is 3.41 s.

Then, the velocity of the car traveling over the cliff is calculated as

                                            [tex]v = \frac{point of impact}{t} \\\\v = \frac{130}{3.41} \\\\v = 38.12 m/s[/tex]

The velocity of the car traveling when it went over the cliff is 38.12 m/s.

Answers

The emf of the battery is 7.2 volts when the internal resistance of a battery is 2 ohms. when a resistance of 10 ohms is connected to the battery, it draws a 0.6 amp current.

Given,

Internal resistance, r = 2 ohms

Resistance connected, R = 10 ohms

Current, i = 0.6 amp

let emf = V

Using ohm's law in the circuit

V = i(r+R)

or V = 0.6(2+10) = 0.6 x 12

V = 7.2 volts

Therefore, the emf of the battery is 7.2 volts when the internal resistance of a battery is 2 ohms. when a resistance of 10 ohms is connected to the battery, it draws a 0.6 amp current.

Everyone was expected to show skill in using words well. Early Heian writers composed artful poems in Chinese, but as time passed, distinctly Japanese ways of writing developed both in daily life and in the creation of works of literature.Writing in Daily Life Poetry was part of daily life in Heian-kyo, and people were expected to compose poetry in public. If they could not think up a few clever lines to fit an occasion, others noticed the failure. Men and women carefully created poems to charm each other. When someone received a poem from a friend, family member, or acquaintance, he or she was expected to write one in response. The responding poem was supposed to be written in the same style and mood, and have the same imagery, as the original.In earlier times, the Japanese had used kana, which was based on simplified Chinese characters, to write the syllables of their language. In Heian times, there were two ways of writing, much like we have cursive and print letters in English. One, katakana, was more formal. Men used katakana when they wrote anything important. The second form of writing was hiragana. Characters in hiragana are formed with simple strokes that make writing and reading easier and faster. Hiragana was mostly seen as women's writing. Court women favored hiragana for personal writing, such as diaries, and some of them used it to create lasting works of literature. Over time, hiragana took its place alongside katakana as part of Japan's written language.Heian writers took care to present their work in a beautiful manner, since calligraphy skills were viewed as important as the ability to create poetry. People believed that handwriting revealed their character and goodness better than the words they used. Calligraphy was often displayed on colorful, handmade paper, and sometimes the paper was even perfumed.Women Become Japan's Leading Writers The female companions to the courtiers of Heian-kyo were usually selected for their intelligence. They often took a great interest in literature, and as a result, women led in the flowering of Japanese literature in the golden age of the 10th and 11th centuries.The best-known Heian writer was Murasaki Shikibu, often referred to as Lady Murasaki. Born into the Fujiwara family, she served as a lady-in-waiting to one of the daughters of Fujiwara Michinaga. Her novel, the Tale of Genji (GEN-jee), is a Heian masterpiece and is today considered one of the great works of world literature.The Tale of Genji is often called the world's first novel. The book follows the life of Genji, a fictional prince, and paints a vivid picture of life in the Heian court. Much of the book focuses on the thoughts and feelings of the characters, particularly the women. For this reason, the Tale of Genji has served as a model for the modern romance novel.Murasaki also kept a diary about her life in the court. Like her novel, her diary offers a close look at court life in the period.The other leading writer of the time was Sei Shonagon. Like the Tale of Genji, Shonagon's Pillow Book presents a detailed picture of life in Heian-kyo. Pillow Book is a collection of clever stories, character sketches, conversations, descriptions of art and nature, and various lists.
