Question

[9] In relativistic particle collisions or decays,

A) momentum and energy are still conserved.

B) momentum and energy are conserved from frame to frame.

C) the mass of a particle is different for various observers.

D) the energy equals the sum of the momentum, pc, plus the mass, mc2.

E) only energy is conserved. Conservation laws in Relativity

[10] Particles with mass are prevented from moving at the speed of light by

A) the shock wave or “light boom” that builds up as light waves bunch up.

B) the increasing cost in energy as they approach the speed of light.

C) the laws of relativity enforced by the physics police.

D) the contraction of their length to zero. E) time slowing to a stop.

Relativistic inertia

[8] A mixture of two gases is kept at a uniform temperature. The particles in the mixture

a) all have the same speed. Kinetic Molecular Theory, Temperature

b) all have the same average speed.

c) have a higher average speed for the lighter mass particles.

d) have a lower average kinetic energy for the more massive particles.

[9] The temperature of a solid is brought to the melting point. While the solid is melting,

a) the temperature remains the same until it is melted. Phase changes

b) the molecules in the liquid have a higher kinetic energy than those in the solid.

c) the molecules in the solid aren’t moving until they enter the liquid phase.

d) The heat added all goes to increased kinetic energy of molecules in the liquid phase.

9)momentum and energy will be. Conserve for rest mass of frame. Therefore option b is correct

10)if Particle of some mass moves with the speed of light then it's length contracts to zero also time gets stop

8)according to kinetic theory of gases all particle moves with the constant or same speed so a option is correct

9)yes when any temperature applied on solid to brought it to liquid then all heat added up and increase its kinetic energy
