A. position: −15 m; displacement: 70 m
B. position: 5 m; displacement: 10 m
C. position: 5 m; displacement: −70 m
D. position: −15 m; displacement: −10 m

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

An object weighs 40n in air, weighs 20n when submerged in water and 30n when submerged in a liquid of unknown density. what is the density of the liquid?
