Selena uses a garden hose to fill a bucket of water.  The water enters the hose through a faucet with a 6.0-cm diameter.  The speed of the water at the faucet is 5 m/s.  If the faucet and the nozzle are at the same height, and the water leaves the nozzle with a speed of 20 m/s, what is the diameter of the nozzle?
