Answers

Answer 1

From insulating threads, two thin metal spheres are suspended close to one another. One sphere has a net charge while the other sphere has no net charge. The spheres will exert no net electrostatic force on each other. The correct option is A.

The uncharged balloon in an experiment advances toward the charged rod. The net charge from the charged sphere distributes onto both evenly, so they are each charged with same sign. The positive and negative charges neutralise, any residual charge is spread evenly. So, both spheres are charged with same sign. If there is no residual charge, both remain neutral.

Suppose the sphere is positively charged, the neutrally charged sphere becomes is negatively charged. The other sphere is polarised by the positively charged one, with a negative charge on the side that is nearest to the first sphere. Now the second sphere moves towards the first sphere.

What is elastic collision?

This is a type of collision in which the two objects move with a different velocities after the collision.

In elastic collision both momentum and kinetic energy is conserved unlike the inelastic collision where only momentum is conserved and the kinetic energy of the system is not conserved.

Thus, we can conclude that in an isolated system during elastic or inelastic collision the sum of the initial momentum of the system is equal to the sum of the final momentum of the system.

Velocity Meaning

According to the velocity meaning, it can be defined as the rate of change of the object’s position with respect to a frame of reference and time. It might sound complicated, but velocity is basically speeding in a specific direction. It is a vector quantity, which means we need both magnitude (speed) and direction to define velocity. The SI unit of it is metre per second (ms-1). If there is a change in magnitude or the direction of the velocity of a body, then it is said to be accelerating.

Initial and Final Velocity

Initial velocity describes how fast an object travels when gravity first applies force on the object. On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.

a small, 300 g cart is moving at 1.20 m/s on a frictionless track when it collides with a larger, 4.00 kg cart at rest. after the collision, the small cart recoils at 0.870 m/s . What is the speed of the large cart after the collision? Express your answer to three significant figures and include the appropriate units.

Answers

Answer:

The speed of the large cart after the collision is 0.0248 m/s.

Explanation:

In this example we will use the Conservation of Momentum.

The Conservation of Momentum states that the momentum of a system is remains the same if no external forces are acting on the system.

Our question is an example of a partially elastic collision.

In a partially elastic collision momentum is conserved and the 2 objects move at different speeds. Kinetic energy is not conserved.

We can come up with an equation for this situation

[tex]m_1V_{i1} +m_2V_{i2}=m_1V_{f1} +m_2V_{f2}[/tex]

Let the small cart be object 1 and let the large cart be object 2.

Convert 300 grams to kilograms.

1 kg = 1000 g

0.3 kg = 300 g

We are given

[tex]m_1=[/tex] 0.3 kg

[tex]V_{i1} =[/tex] 1.20 m/s

[tex]m_2=[/tex] 4.00 kg

[tex]V_{i2} =[/tex] 0 m/s

[tex]V_{f1} =[/tex] 0.870 m/s

Inserting our values into the equation gives us

[tex](0.3*1.2)+(4*0)=(0.3*0.870)+(4*V_{f2})[/tex]

Lets simplify and evaluate [tex]V_{f2}[/tex].

Anything multiplied by 0 is equal to 0

[tex](0.3*1.2)=(0.3*0.870)+(4*V_{f2})[/tex]

Evaluate each set of parenthesis.

[tex]0.36=0.261+4V_{f2}[/tex]

Subtract [tex]0.261[/tex] from both sides of the equation.

[tex]0.099=4V_{f2}[/tex]

Divide each side of the equation by 4.

An object can encounter some resistance when moving through the fluid medium of air.

The drag force is the oppositional force applied by the air to a moving object. The size of the cross section A of the front face of the item, the density of the air, and the square of the object's velocity v all contribute to the drag force.

With motion exclusively in the vertical direction and letting

downward be positive, we have that

dv/dt = g - pv, where g = 32 ft/, and so

dv/dt + pv = g. The integrating factor is , so

d/dt( × v) = g× ----->

v = (g/p)× + C ----->

v(t) = (g/p) + C×

Now v(0) = (g/p) + C = 0, and so C = -g/p, giving us

v(t) = (g/p)×(1 - ).

Now we are given that lim(t->infinity)(v(t)) = 99 mi/h = 145.2 ft/s,

so since -> 0 as t -> infinity we have g/p = 145.2 ft/s ------>

p = 32 ft/s^2 / (145.2 ft/s) = 0.2204 s^-1 .

Next, since we have defined downward as positive, the expression

we have for v(t) will equal dy/dt where y(0) = 0 and y increases as

the paratrooper falls. So

dy/dt = v(t) = (g/p)×(1 - )), so

y(t) = (g/p)×(t + (1/p)×) + K.

Now y(0) = (g/p)×(0 + (1/p)) + K = 0 ----->

K = -(g/p^2) = 32 / 0.2204^2 = -658.76 ft, so

y(t) = (145.2)×(t + (4.5372)×e^(-0.2204×t)) - 658.76.

Next, y(6) =  (145.2)×(6 + (4.5372)×e^(-0.2204×6)) - 658.76 = 444.84 feet.

WHY do stars turn hydrogen into heavier elements such as helium, beryllium etc?

Answers

Answer: Stars turn hydrogen into heavier elements through a process called nuclear fusion. This occurs when the nuclei of hydrogen atoms come together under intense heat and pressure, releasing a large amount of energy in the form of light and heat. This process is triggered by the intense gravity at the core of a star and continues until the star runs out of fuel and eventually dies.

Explanation:

The fusion of hydrogen nuclei uses up hydrogen to produce helium and energy. Hydrogen is the fuel for the process. As the hydrogen is used up, the core of the star condenses and heats up even more. This promotes the fusion of heavier and heavier elements, ultimately forming all the elements up to iron.

0.594 moles of air were collected from the plane flying at an altitude of 30,000 feet and is at a temperature of -35.0 C.

What is temperature?

Temperature is the measure of the average kinetic energy of the particles in a substance. It can be measured in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K). Temperature is an important physical property of matter, as it can affect the state of a substance.

The total moles of air in the container is 45.0 L * (1.00 mol/22.4 L) = 2.01 mol.
Since the sample is 75.56% nitrogen, 23.15% oxygen, and 1.29% argon, the moles of each are:
Nitrogen = 0.7556 * 2.01 mol = 1.52 mol
Oxygen = 0.2315 * 2.01 mol = 0.46 mol
Argon = 0.0129 * 2.01 mol = 0.03 mol
The 0.594 moles of air collected from the plane is the difference between the total moles and the moles of nitrogen, oxygen, and argon:
Air = 2.01 mol - 1.52 mol - 0.46 mol - 0.03 mol = 0.594 mol

Answers

The distance which the sled which is weighing 32 kg and has a speed of 5.5 m/s will travel before stopping is 15.1 meters.

What is Friction?

Friction is the force which resists the sliding or rolling of one solid object over the another object. Frictional forces, such as the one traction needed to walk without slipping, may be beneficial, however they also present a great measure of opposition to the motion of object.

In this problem, we are to utilize the kinematic equation in the form;

Vf² = Vi² + 2aD

where, Vi is the initial velocity, Vf is the final velocity, a is the acceleration and D is the distance traveled.

Given,

Mass of boy and sled (m) = 32 kg

Speed of boy and sled (Vi) = 5.5 m/s

Average force (F) = 32 N

Using the equation for Newton's Second Law of Motion with the friction force opposing the motion:

Fs = ma

a = Fs/ m

a = -32/ 32

a = -1m/s²

Plugging the values in the obtained acceleration into the kinematic equation, we get:

(0)² = (5.5)² + 2(-1)D

D = (5.5)²/ 2

D = 30.25/ 2

D = 15.1 meters

Answers

The Debye length is calculated as λD = (1/1.00 * 10^-5 mol/l * 298 K)^(1/2) = 28.6 Å.

What is length?

Length is a measure of distance between two points, usually denoted by the unit of measurement being used. It can be measured in a variety of ways, including in meters, miles, centimeters, or inches. Length can also be used to measure the size or dimensions of an object, such as the width of a table or the height of a building. Length can also be used to measure time, such as in seconds or minutes.

The Debye length in a sample of distilled water with an ionic strength of 10.0 µM is approximately 28.6 Å (2.86 * 10^-9 m). This value is calculated using the Debye-Hückel approximation, which states that the Debye length λD is equal to the square root of the inverse of the ionic strength I multiplied by the temperature T, i.e. λD = (1/I*T)^(1/2).
