1 answer:
Compute the work done on the table:
<em>W</em> = <em>Fd</em> = (320 N) (32 m) = 10,240 J
Divide this by the given time duration to get the power output:
<em>P</em> = <em>W</em>/∆<em>t</em> = (10,240 J) / (150 s) ≈ 63.3 W

You need to know the formula:
25 = 1/2 * g * t^2
t = √(50/g) = 2.258 s, where I use g = 9.8 m/s^2
That's called wave <em>REFRACTION</em>.
Answer:
0.364
I believe... Good luck!
Need a picture of the problem
The convection currents in the mantle caused the crust on top to break apart & go different directions.
