Q1. You bring a 350-g wrench into the house from your car. The house is 15 C warmer than the car, and it takes 2.52 kJ of energy to warm the wrench by this amount. Find (a) heat capacity of the wrench and (b) specic heat of the metal it's made from.

Q2. A small sphere of charge q1 = 0.768 µC hangs from the end of a spring (a). When another small sphere of charge q2 = -0.648 µC is held beneath the first sphere.

(b). spring stretches by d = 3.84 cm from its original length and reaches a new equilibrium position with a separation between the charges of r = 4.65 cm. What is the force constant of the spring?
