An object has a kinetic energy of 77j and a mass of 52 kg, how fast is the object moving?

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

An object of dimensions 50 cm x 40 cm x 0.20 cm has a mass 60g. find its density in g/cm3 and kg/ m3
