Answer:
10
Explanation: Earth takes 24 hours to complete one spin, and Mars takes 25 hours. The gas giants rotate really fast. Jupiter takes just 10 hours to complete one rotation. Saturn takes 11 hours, Uranus takes 17 hours, and Neptune takes 16 hours.
I believe this would be an example of Mary's velocity. We have her speed and direction which is all you need to find velocity.
Answer:
Power generate by generator = 265 W (Approx.)
Explanation:
Given:
Mass of student = 62 kg
Height of stairs = 3.4 meter
Time taken = 7 second
Find:
Power generate by generator
Computation:
Power = Force x [Distance / Time]
Power = [Mass x gravitational acceleration] x [Distance / Time]
Power = [62 x 9.8][3.4/7]
Power = [607.6][3.4/7]
Power = 265.12
Power generate by generator = 265.12
Power generate by generator = 265 W (Approx.)
