Describe the relationship between energy and wavelength.
The energy of a wave is inversely proportional to its wavelength
The energy of a wave is proportional to its wavelength
The energy of a wave is constant as wavelength increases.
The energy of a wave is constant as wavelength decreases.
What happens to the period and frequency of a wave as you move from gamma to radio waves?
Period decreases; frequency decreases
Period increases; frequency decreases
Period increases; frequency increases
Period increases; frequency remains constant

Compare and contrast Newton's theory to Coulomb's theory.
Newton's theory involves gravitational forces due to mass, Coulomb's theory is due to electrostatic forces
Newton's theory involves electrostatic forces due to mass, Coulomb's theory is due to gravitational forces
They are the same theory
Newton's theory involves attraction and repulsion while Coulomb's theory discusses only attraction

30 N of force to the left
30 N of force to the right
If 2 runners are on tracks and runner A is moving at a constant speed of 15 m/s and runner B is moving at a constant speed of 20 m/s. What can we conclude?
Runner B's track has a larger radius
Runner A's track has a larger radius
Runner B's centripetal force is greater
Runner A's centripetal force is greater
What is the relationship between displacement and gravity?
Displacement is always positive because gravity never pushes in the opposite direction
Displacement will always be positive because it can never be less 0
Displacement will always be negative due to a downward direction
Newton decided displacement would always be positive
