Question
If the height of water behind a dam is increased by a factor of two, then the maximum kinetic energy of the water at the bottom of the dam will increase by a factor of ____. one two four zero The net force required to move a body at a constant velocity in outer space is ______. zero its weight the force of gravity its mass times its velocity the force of friction Power is defined as _____. the energy used times the time the work done times the distance of motion the energy used divided by the work the rate of converting energy the ability to do workExplanation / Answer
17] b
when height is increased by factor of two, potential energy doubles at top, so KE at bottom also doubles.
18]a F=ma
19]d power = energy/time
