If the average translational kinetic energy of the molecules of one sample of gas has twice the value of that of another sample of gas, how do the internal energies of the two gases compare?
1.The internal energy of the first gas is greater.
2.The internal energy of the second gas is greater.
3.The internal energies of both gases are the same.
4.We cannot determine which gas has the greater internal energy.

Ultraviolet light is shone on a piece of metal that has a known work function, and electrons are observed being produced through the interaction of the light with the metal.

A. Fewer electrons per unit time are produced. B. More electrons per unit time are produced. C. Nothing changes at all. D. Electrons with a higher maximum energy are observed. E. Electrons with lower maximum energy are observed.
Hubble's Law (also known as the Hubble-Lemaitre Law) can be restated as:
A. The mass-to-light ratio of a spiral galaxy is greater if its rotational velocity is also greater. B. The more distant a galaxy, the faster it is receding. C. The rotation curve of a galaxy is related to the amount of mass inside. D. The velocity curves of spiral galaxies only make sense if there exists a lot of unseen matter.
