Answer: What is this supposed to be converted into?
Explanation:
It'd be an unbalanced force
Answer:heat brings it up then down
Explanation:
Time t = ?
<span>When wave is moving from
y = 0 to y =12 cm</span>
By using the formula,
y = 15cos [(π/12) t)] =
0,
cos [(π/12) t)] = 0 =
cos (π/2), so,
(π/12)t = π/2,
t = (π/2) (12/π)
t = 12/2
<span>t = 6 sec</span>
<span>so 6 sec is the least amount of time required</span>
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.)
