Two cubes, one silver and one iron, have the same mass and temperature. a quantity q of heat is removed from each cube. which one of the following properties causes the final temperatures of the cubes to be different?

a) density
b) latent heat of vaporization
c) specific heat capacity
d) coefficient of volume expansion
e) volume

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
