What are control rods in a nuclear reactor?

	they serve to fuel the nuclear reaction
	they are used for emergency notification
	they absorb energy from the reaction to transmit
	they control the intensity of the chain reaction

Who was the first scientist to include electrons in the atomic model?

What are the pros and cons of nuclear fission?

The energy levels for a Bohr atom are shown below.

What amount of energy is needed for an electron to jump from n = 1 to n = 3? (h = 6.626 x 10^-34, 1 eV = 1.6 x 10^-19 J)

Which scientist defined the areas of probability of where electrons can be found orbiting the nucleus of an atom?

A photon has 1.86 eV of energy. What is the photon's wavelength? (h = 6.626 x 10^-34, 1 eV = 1.6 x 10^-19 J)

This scientist theorized that electrons could only orbit at specific distances and that atomic model included shells of specific energies.

Which of the following was Einstein's Second Postulate to the Special Theory of Relativity?

	Waves had to have some medium to travel through.
	The laws of physics are the same in all frames of reference that are moving uniformly.
	The speed of light is constant and is independent of the motion of the source or the observer.
	A beam of light that traveled parallel to the aether would take longer than the beam that traveled perpendicularly to the aether.

Which of the following best describes a frame of reference?

	the theory that describes the behavior and characteristics of objects moving at relativistic speeds
	the effect of the slowing of time as an object moves with high speeds
	a point in which someone relates the behavior of an object from one perspective
	an experiment that proved that Earth did not have an aether wind
