[tex]1.50 \times 10^{22}[/tex]  mercury atoms emit a photon during this one second of operation

The steps shown below can be used to resolve this issue:

Find the energy of a photon of light with a 253 nm wavelength. The formula is as follows:

E = hc/λ

where E denotes the photon's energy, h denotes Planck's constant (6.626 x  [tex]10^{-34}[/tex] J s), c denotes the speed of light (2.998 x [tex]10^8[/tex]m/s), and denotes the photon's wavelength in metres.

Inputting the values provided yields:

E = (6.626 x [tex]10^{-34}[/tex] J s) x (2.998 x [tex]10^8[/tex]m/s) / ([tex]253 \times 10^{-9}[/tex] m)

E = 7.87 x [tex]10^{-19}[/tex] J

Hence, a photon of light with a wavelength of 253 nm has an energy of 7.87 x[tex]10^{-19}[/tex] J.

Count the number of photons the light emits in a second. The formula is as follows:

number of photons = energy of light / energy of one photon

Substituting the given values, we get:

number of photons = 11.8 J / [tex]7.87 \times 10^{-19}[/tex] J

number of photons = [tex]1.50 \times 10^{22}[/tex] photons

Therefore, the lamp emits [tex]1.50 \times 10^{22}[/tex] photons in one second.

Find the quantity of mercury atoms that release a photon every second. The number of mercury atoms is equal to the number of photons released by the lamp since each photon represents the emission of one mercury atom:

number of mercury atoms = number of photons

number of mercury atoms = [tex]1.50 \times 10^{22}[/tex]  atoms

As a result, during one second of operation, the low-pressure mercury-vapor lamp emits [tex]1.50 \times 10^{22}[/tex] mercury atoms.

Object 2 has a greater final speed of  52.5 Ns / mass or 13.125 m/s while object 1 has a final speed of only 50 Ns / mass or 6.25.

In physics, an influence that causes motion of an object with mass to change its velocity is known a s force.

Solving for final speed of object 1

As, final speed = initial speed + acceleration * elapsed time.

So, final speed   = 0 + (Force / mass) * elapsed time

final speed = 0 + (25 N/mass) * 2 s

So, final speed of object 1 = 50 Ns / mass

Solving for final speed of object 2

As, final speed = initial speed + acceleration * elapsed time

final speed = 0 + (35 N / 2 * mass) * 3 s

final speed = 17.5 N * 3 s / mass

So, final speed of object 2 = 52.5 Ns / mass

If object 1 has  mass of 4 kg then object 2 has mass of 8 kg.

Increasing the volume would decrease the pressure of a contained gas.

Option (D) will be correct.

According to the ideal gas law, the pressure (P) of a contained gas is directly proportional to the number of particles (n) and the temperature (T), and inversely proportional to the volume (V).

The ideal gas law is a fundamental equation of state in thermodynamics that describes the behavior of an ideal gas. It relates the pressure (P), volume (V), number of moles (n), and temperature (T) of a gas through the equation: PV = nRT where R is the gas constant, a universal constant that depends on the units used for P, V, n, and T.

The ideal gas law assumes that the gas is composed of a large number of tiny particles in constant random motion, that there are no intermolecular forces between the particles, and that the particles occupy no volume. This implies that the particles are considered as point masses, and that their collisions with each other and with the walls of the container are perfectly elastic.

The direction of acceleration of the flea is 0.0376 degrees relative to the vertical.

The net force on the flea can be found by vector addition of the forces F1 and F2:

Fnet = F1 + F2

The forces F1 and F2 are given as:

F1 = 1.2 × 10^-5 N (straight down)

F2 = 0.515 × 10^-6 N (parallel to the ground)

We can resolve F1 into its horizontal and vertical components. The vertical component of F1 is equal and opposite to the weight of the flea, which is given by:

W = mg

= (6 × 10^-7 kg) × (9.8 m/s^2)

= 5.88 × 10^-6 N

Therefore, the vertical component of F1 is -5.88 × 10^-6 N (upwards), and the horizontal component of F1 is zero.

The forces F2 and the vertical component of F1 are both parallel to the ground, so their vector sum is simply the sum of their magnitudes:

Fnet = F1v + F2

= (-5.88 × 10^-6 N) + (0.515 × 10^-6 N)

= -5.365 × 10^-6 N

The negative sign indicates that the net force is upwards, opposite to the direction of the flea's motion.

Now, we can use Newton's second law of motion to find the acceleration:

Fnet = ma

Rearranging this equation, we get:

a = Fnet/m

Substituting the values of Fnet and m, we get:

a = (-5.365 × 10^-6 N) / (6 × 10^-7 kg)

= -8.942 m/s^2

The negative sign indicates that the acceleration is upwards, opposite to the direction of the flea's motion.

Finally, we can find the direction of the acceleration relative to the vertical using trigonometry. The vertical component of the acceleration is given by:

aV = -a sin θ

where θ is the angle between the direction of acceleration and the vertical. Rearranging this equation, we get:

sin θ = -aV / a

Substituting the values of aV and a, we get:

sin θ = (-5.88 × 10^-6 N) / (-8.942 m/s^2)

= 0.000656

Taking the inverse sine, we get:

A) The rms speed of the gas increases by a factor of √2.

B) The mean free path of the gas decreases by a factor of 2.

C) The thermal energy of the gas remains constant.

D) The molar specific heat at constant volume increases by a factor of 5/3.

The rms speed of a gas is proportional to the square root of its temperature. Since the compression is adiabatic (i.e., no heat is added or removed from the gas), the temperature of the gas increases by a factor of 2 when its volume is compressed to 0.125 of its initial volume. Thus, the rms speed increases by a factor of √2.

The mean free path of a gas is inversely proportional to its pressure. Since the pressure of the gas increases by a factor of 8 (i.e., 1/0.125) when its volume is compressed to 0.125 of its initial volume, the mean free path decreases by a factor of 2.

The thermal energy of a gas is proportional to its temperature and the number of particles (i.e., the amount of gas). Since the temperature remains constant and the number of particles does not change during the adiabatic compression, the thermal energy of the gas remains constant.

The molar specific heat at constant volume of a monatomic gas is 3/2 R, where R is the gas constant. Since no work is done during the adiabatic compression, all the work done on the gas is converted into an increase in internal energy. Thus, the temperature of the gas increases by a factor of 2, and the molar specific heat at constant volume increases by a factor of 5/3.

Answer:

Explanation:

Total force is the vector sum of the individual forces.

This is an example of an inelastic collision. In an inelastic collision, some of the initial kinetic energy is lost, and the objects move away from each other with a reduced speed, as is the case here.

Collision is the physical contact between objects, causing them to interact and exchange energy. This can occur when two or more objects come into contact with each other while moving at different speeds. Collisions can be elastic or inelastic, depending on the type and amount of energy lost in the interaction. Elastic collisions are those in which the total kinetic energy of the objects is the same before and after the collision, while in inelastic collisions some energy is lost in the form of heat, sound, or other forms of energy.

The centripetal acceleration of the rock can be calculated using the formula:

a = v^2 / r

where v is the tangential velocity and r is the radius of the circle.

Substituting the given values, we get:

a = (12.56 m/s)^2 / 1m = 157.93 m/s^2

Rounding to the hundreds place, the centripetal acceleration of the rock is approximately 157.93 m/s^2.

The final velocity of the coupled freight cars after the collision is -1.0 m/s, which means that they are moving to the left with a speed of 1.0 m/s.

To solve this problem, we can use the principle of conservation of momentum, which states that the total momentum of a system of objects is conserved if there are no external forces acting on the system. In this case, the two freight cars are the system, and the collision is assumed to be perfectly elastic, which means that the total kinetic energy of the system is conserved as well.

Let the positive direction be to the right, and the negative direction be to the left. Then, the initial momentum of the system is:

p_initial = m1v1 + m2v2

= 6000 kg * 2.0 m/s + (-3000 kg) * 3.0 m/s

= 6000 kgm/s - 9000 kgm/s

= -3000 kg*m/s

where m1 and v1 are the mass and velocity of the loaded car, and m2 and v2 are the mass and velocity of the empty car. The negative sign indicates that the momentum of the empty car is in the opposite direction to that of the loaded car.

After the collision, the two freight cars will move together as a single unit with a common velocity v_final. Since the total momentum of the system is conserved, we can write:

p_final = (m1 + m2) * v_final

where m1 + m2 is the total mass of the system. Setting the initial and final momenta equal and solving for v_final, we get:

v_final = p_initial / (m1 + m2)

= (-3000 kg*m/s) / (6000 kg + 3000 kg)
