Using .125 mass kgwhat is the velocity

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

6–48 bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.

What do we mean by the event horizon of a black hole?
