The lowest temperature ever recorded in Alaska is −62°C. The highest temperature ever recorded in Alaska is 38°C. Suppose a piece of metal with a
mass of 180 g and a temperature of −62.0°C is placed in a calorimeter
containing 0.500 kg of water with a temperature of 38.0°C. If the final
equilibrium temperature of the metal and water is 36.9°C, what is the specific
heat capacity of the metal? Use the calculated value of the specific heat
capacity and Table 4 in your textbook to identify the metal

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.
