A hydroelectric power station generates electricity using water from a high-level reservoir.
Write down the equation which links density (ρ\rhoρ), mass (mmm), and volume (VVV).
The reservoir stores 5,400,000 m35,400,000\text{ m}^35,400,000 m3 of water. The density of the water is 997 kg/m3997\text{ kg/m}^3997 kg/m3. Calculate the mass of water in the reservoir. Give your answer in standard form.
Write down the equation which links energy transferred (EEE), power (PPP), and time (ttt).
The station's electrical generators can provide 1.8×109 W1.8 \times 10^9\text{ W}1.8×109 W of power for a maximum of 4 hours4\text{ hours}4 hours. Calculate the maximum energy that can be transferred by these generators. Give your answer in standard form.
