how does the energy of ultraviolet radiation compare to the energy of microwaves?
uv radiation has less energy than microwaves, because uv radiation has a lower frequency.
uv radiation has more energy than microwaves, becuse uv radiation has a higher frequency.
microwaves have less energy than uv radiation, because microwaves have shorter wavelengths.
microwaves have more energy than uv radiation, because microwaves have longer wavelengths.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
