You cool a hot piece of iron by dropping it in cool water. which statement incorrectly describes what is happening? a) after enough time, the final temperature of the water and iron will be the same
b) the amount of heat gained by the water equals the amount of heat lost by the iron
c) the temperature of the iron will decrease as the temperature of the water increases
d) the temperature change of the iron will depend on the latent heat of iron

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.
