Q1. A heavy piece of hanging sculpture is suspended by a 94 cm long, 4.6 g steel wire. When the wind blows hard, wire hums at its fundamental frequency of 80 Hz. What is the mass of the sculpture?

Q2. When one gallon of gasoline is burned in a car engine, 1.18 x 10^8 J of internal energy is released. Suppose that 0.99 x 10^8 J of this energy flows directly into the surroundings (engine block and exhaust system) in the form of heat. If 6.0 x 10^5 J of work is necessary to make the car goes one mile, how many miles can car travel on one gallon of gas?
