The statement that best explains why the system looses energy is; the Collison of the molecules of hydrogen with the wall of the can carries off energy to the environment.

We know that energy is defined as the rate of doing work. Now the temperature of a gas is measure of the kinetic energy of the molecules of the body. In this case, the temperature of the hydrogen in the cannister has to do with how fast the molecules of the hydrogen are moving.

The higher the temperature, the faster the molecules of the hydrogen move. The lower the temperature, the slower the molecules of the hydrogen moves.

As such, the molecules collide with the walls of the canister, causing the canister molecules to vibrate and carry energy from the canister to the canister’s surroundings.

What is internal energy and an illustration?

The term "internal energy" describes the power contained in all of the chemical bonds that hold a system's molecules together as well as the kinetic energy of the molecules themselves. Every time heat, work, and internal energy interact, there is a transfer of energy and a conversion.

What makes it internal energy?

W. Thomson first used the word in thermodynamics in 1852. (the later Lord Kelvin). Because certain energy contributions are ignored, the adverb "internal" is used. For instance, the entire system possesses kinetic energy when it is moving uniformly.

A) The emf (electromotive force) as a function of time is: ε(t) = -(8.8 - \(1.53t^2)\) × \(10^-^2\) V.

B)The emf at t = 1.1 s is approximately -0.014 V, and at t = 3.1 s, it is approximately -0.311 V.

A) To determine the emf (electromotive force) as a function of time, we need to calculate the rate of change of magnetic flux with respect to time, which is given by Faraday's law of electromagnetic induction.

The emf (ε) is given by the equation ε = -dΦ/dt, where Φ represents the magnetic flux.

Given the magnetic flux through each loop as (8.8t -\(0.51t^3)\) ×\(10^-^2\)T·\(m^2\), we can differentiate it with respect to time to find the rate of change:

dΦ/dt = (d/dt)(8.8t - \(0.51t^3)\) × \(10^-^2\)T·\(m^2\).

Taking the derivative of the above expression, we have:

dΦ/dt = (8.8 - \(1.53t^2)\)× \(10^-^2\) T·\(m^2\)/s.

Thus, the emf as a function of time is:

ε(t) = -(8.8 - \(1.53t^2)\) × \(10^-^2\) V.

B) To find the emf at specific time points, we substitute the given time values into the emf equation.

At t = 1.1 s:

ε(1.1) = -(8.8 -\(1.53(1.1)^2)\)×\(10^-^2\) V.

Calculating the expression inside the parentheses and multiplying by -\(10^-^2\), we find:

ε(1.1) ≈ -0.014 V (rounded to two significant figures).

Similarly, at t = 3.1 s:

ε(3.1) = -(8.8 - \(1.53(3.1)^2)\) × \(10^-^2\) V.

Evaluating the expression inside the parentheses and multiplying by -\(10^-^2\), we obtain:

ε(3.1) ≈ -0.311 V (rounded to two significant figures).

Answer:

The photoelectric effect

The photoelectric effect supports the particle model of light. Hence option A is correct.

When a substance absorbs electromagnetic radiation, a process known as the photoelectric effect causes electrically charged particles to be discharged from or inside the material. When light strikes a metal plate, the action is frequently described as the ejection of electrons from the plate. In a more general definition, the substance may be solid, liquid, or gas, the radiant energy may take the form of infrared, visible, or ultraviolet light, X-rays, or gamma rays, and the discharged particles may include ions (electrically charged atoms or molecules) in addition to electrons. Because of the perplexing concerns it presented about the nature of light—particle versus wavelike behavior—that were eventually answered by Albert Einstein in 1905, the phenomenon was critically important in the development of modern physics.

The coefficient of kinetic friction turns out to be 0.534 whereas the coefficient of static friction is 0.595.

(a) mass = m = 6 kg

   g = 9.81 m/s^2

   F =  k m g

k = F / m g  = 35 / ( 6  * 9.81 ) = 0.595

The box can't move on its own because of static friction; this friction must be overcome by an opposing force that is strong enough for the box to move. When surfaces are moving, a force called kinetic friction, also known as dynamic friction, opposes the relative movement of the surfaces.

A force that holds an item at rest is called static friction. The friction that people experience when attempting to move a stationary object on a surface without actually causing any relative motion between the body and the surface is defined as:

MASS AND ACCELERATION

Explanation:

Newton's Second Law of Motion addresses the relationship between MASS AND ACCELERATION that influence the force on a body

The magnetic field vector at point D will be B = Bx i + By j = (-3.83 × 10⁻⁵ T) i + (1.67 × 10⁻⁵ T) j.

Part A: At point A, the magnetic field vector produced by the moving point charge will be in the z-direction and can be calculated using the formula for the magnetic field of a moving point charge. The magnitude of the magnetic field can be calculated using the formula

B = μ₀qv/4πr²,

where μ₀ is the permeability of free space, q is the charge, v is the velocity, and r is the distance from the charge.

Substituting the given values,

we get

B = (4π × 10⁻⁷ T·m/A)(6.00 × 10⁻⁶ C)(8.00 × 10⁶ m/s)/(4π(0.5 m)²)

  = 3.83 × 10⁻⁵ T, directed in the positive z-direction.

Part B: At point B, the magnetic field vector produced by the moving point charge will be in the x-direction and can be calculated using the same formula as in Part A.

Substituting the given values, we get

B = (4π × 10⁻⁷ T·m/A)(6.00 × 10⁻⁶ C)(8.00 × 10⁶ m/s)/(4π(0.5 m)²)

  = 3.83 × 10⁻⁵ T,

directed in the negative x-direction.

Part C: At point C, the magnetic field vector produced by the moving point charge will be in the y-direction and can be calculated using the same formula as in Part A. Substituting the given values, we get

B = (4π × 10⁻⁷ T·m/A)(6.00 × 10⁻⁶ C)(8.00 × 10⁶ m/s)/(4π(0.5 m)²)

  = 3.83 × 10⁻⁵ T,

directed in the positive y-direction.

Part D: At point D, the magnetic field vector produced by the moving point charge will have both x and y components and can be calculated using vector addition of the individual components. The x-component will be the same as in Part B, i.e., Bx = -3.83 × 10⁻⁵ T.

The y-component can be calculated using the formula

By = μ₀qvz/4πr³,

where vz is the velocity component in the z-direction. Substituting the given values, we get

By = (4π × 10⁻⁷ T·m/A)(6.00 × 10⁻⁶ C)(8.00 × 10⁶ m/s)(0.5 m)/(4π(0.5² + 0.5²)³/2)

   = 1.67 × 10⁻⁵ T,

directed in the positive y-direction.

Therefore, the magnetic field vector at point D would be B = Bx i + By j = (-3.83 × 10⁻⁵ T) i + (1.67 × 10⁻⁵ T) j.

So when we're finally ready to try it, the cannonball and golf ball will make a  kind of cute experiment, but let's make it really interesting.  Let's ALSO try it with a feather, an apple, a watermelon, a tennis ball, a basketball, a coffeepot, a chair, an old computer, a set of dishes, a trombone, a bicycle, a math book, a TV set, a gallon of milk, a skateboard, a shotgun, a concrete block, a car, a waterbed, a schoolbus, a battleship, your dog, and my wife !

Drop every single one of them from a height of 10 meters.

Every single one of them accelerates at 9.8 m/s² as it falls, takes 1.429 seconds to reach the floor, and hits the floor at a speed of 14 m/s.  The feather, the schoolbus, and my wife stay together all the way down.

The only way this doesn't happen is if ...

-- you do this experiment in some other place that's not Earth, or

-- you throw one of the objects and you don't just drop it, or

-- the vacuum chamber has a leak and some air gets into it.

Therefore, the possible values of the azimuthal quantum number of the hydrogen atom, l will be,

l = 0, 1 ,2, ..., (n - 1) = 0, 1, 2, ..., (5 - 1) values

l = 0, 1, 2, 3, 4

So, the hydrogen atom will have 5 values for the azimuthal quantum number.

ii) Given that,

The principal quantum number of hydrogen atom, n = 5

Azimuthal quantum number of the hydrogen atom, l = 3

Therefore, the possible values of magnetic quantum number, m will be,

Answer:

The sound intensity that the other student measure, I₂ is expected to be;

A) 6.2 × 10⁻⁸ W/m²

Explanation:

The measure of sound intensity is given by the following formula;

\(I = \dfrac{P}{4 \cdot \pi \cdot R^2}\)

\(\dfrac{I_2}{I_1} = \dfrac{R_1^2}{R_2^2}\)

Where;

I = The intensity

R = The radius

P = The power of the sound

Whereby we have;

The distance of the two people talking, R₁ = 3.0 m

The measure of the sound intensity, I₁ = 1.1 × 10⁻⁷ W/m² (from an online source)

The distance of the other student from the two people talking, R₂ = 4.0 m

Therefore, the estimate of the sound intensity, I₂, is given as follows;

\({I_2} = \dfrac{R_1^2}{R_2^2} \times {I_1}\)

\({I_2} = \dfrac{(3.0 \, m)^2}{(4.0 \, m)^2} \times 1.1 \times 10^{-7} \ W/m^2 = 6.1875 \times 10^{-8} \ W/m^2\)

I₂ = 6.1875 × 10⁻⁸ W/m²

∴ The sound intensity that the other student measure, I₂ ≈ 6.2 × 10⁻⁸ W/m²
