W = ΔE = 1/2 m (v₂ - v₁)²
W work
E kinetic energy
m mass
v₂ final velocity
v₁ initial velocity
Answer:
The momentum of the basketball is three times that of the softball. Momentum equals mass times velocity. Therefore, if the basketball and softball are moving at the same velocity, and the basketball has three times the mass of the softball, the basketball has three times the momentum of the softball.

The correct answer is
b. low frequencies and low energy.
In fact, microwaves and radio waves have frequency up to
, which are really low compared, for instance, to the frequency of gamma rays (
). Moreover, the energy of an electromagnetic wave is directly proportional to its frequency:

where h is the Planck constant and f the frequency; therefore, low frequency means also low energy.
