Power<span> is the rate of doing work. It is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. We express it as follows:
P = W / t
where W = Fd
F = mg
Therefore,
P = mgd / t
P = (30)(9.81)(20) / 1 = 5886 W</span>
Work done = Mass * displacement
W = 50 * 5 = 250 watts
In short, Your Answer would be 250 watts
Hope this helps!

There's a few differences. In a physical change the actual substance doesn't change, where in a chemical change with chemical reaction, a new substance is formed. Physical change can be reversed, and chemical change can't.
