A dam is used to block the passage of a river and to generate electricity. Approximately 5.73 × 104 kg of water fall each second through a height of 19.6 m. If 85 % of the gravitational potential energy of the water were converted to electrical energy, how much power would be generated?

9.36 MW

Explanation:

Let g = 9.81 m/s2. Then the gravitational energy of that much water at a height of 19.6 m is as following

per second or 11017414.8 W

If only 85% of this energy is converted to electrical energy then the power generated would be

11017414.8 * 85% = 9364802.58 W or 9.36 MW

b

explanation:

bc its just b

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
