The energy of a UV wave from the sun becomes part of the internal energy
of the sidewalk causing the sidewalk to heat up, then the wave's energy
was *
a) absorbed
b) transmittted
c) reflected

a. absorbed

Explanation:

This is because for the internal energy of the sidewalk to increase, its temperature and thus its internal energy must increase. This causes it to heat up and this is done by absorbing energy from the UV wave.

another example of kinetic energy would be,

kinetic energy   >     moving energy
