You are going to wash the skylights in your kitchen. The skylights are 7.6 m above the ground. You connect two garden hoses together-a 0.80-cm- radius hose to a 1.0-cm-radius hose. The smaller hose is held on the roof of the house and the wider hose is attached to the faucet on the ground. The pressure at the opening of the smaller hose is 1 atm, and you want the water to have the speed of 6.0 m/s.
