Answer:
195
Explanation:
he can only apply as much force as his body mass so it would be 195
Because of friction
, NOT all potential energy is converted to kinetic energy. (B)
Some of the object's potential energy is converted to heat and lost.
The statement above is true. The phase of matter which is exposed to normal atmospheric pressure is indeed solely dependent upon temperature. If the matter is exposed to the normal atm pressure, its temperature depends on it.
Explanation:
Incident light makes an electron oscillate. The electrons emit light or absorb the light, collide with other electrons, thereby converting light energy to more internal energy. and convert it to heat.
Light wave of a given frequency is incident on a material with electrons having the same vibrational frequencies, then electrons absorb the energy of the light wave and transform it into vibrational motion.
