HELP! The Washington Monument is 555 feet tall. 1. If 1 meter = 3.28 feet, what is the height of the Washington Monument in meters? 2. A worker assigned to the restoration of the Washington Monument is checking the condition of the stone at the very top of the monument. A nickel with a mass of 0.005 kg is in her shirt pocket. What is the gravitational potential energy (GPE) of the nickel at the top of the monument? 3. What is the kinetic energy (KE) of the nickel in her shirt pocket at the top of the monument? 4. If the nickel accidentally falls out of her pocket, what will happen to the gravitational potential energy (GPE) of the nickel as it falls to the ground? 5. If the nickel accidentally falls out of her pocket, what will happen to the kinetic energy (KE) of the nickel as it falls to the ground? 6. A ball is held 1.4 meters above the floor. Use the terms KE of GPE as your answers. 7. When the ball is held motionless above the floor, the ball possesses only energy. 8. If the ball is dropped, its energy decreases as it falls. 9. If the ball is dropped, its energy increases as it falls. 10. In fact, in the absence of air resistance, the amount of energy when the ball is held motionless above the floor equals the amount of energy at impact with the floor.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
