Answer:
0.833
Explanation:
Power = energy / time
Power = force × distance / time
Power = force × velocity
P = (850 kg) (9.8 m/s²) (1.00 m/s)
P = 8330 W
P = 8.33 kW
The efficiency of the motor is therefore:
e = 8.33 kW / 10.0 kW
e = 0.833
More efficient plumbing uses less water and creates smaller volume of waste is the answer why changing your toilet can reduce water pollution. If there is a problem in your toilet, you will use more water. The more water you pour, the more water pollution is added.
KE = 1/2 * m* v^2
= 1/2 * 40 * 225
= 4500 J
