the formula for potential energy is p= mgh, where Pis potential energy, m is mass, g is gravity, and h is height. which expression can be used to represent g?

p = mgh

Solve that for g using algebra. Since in mgh g is multiplied by m and h, do the opposite: divide mgh by m and h. And remember that what you do to one side of an equation you must do the other side as well.

The expression that can be used to represent g (gravity) in the formula for potential energy is "4 p/(mh)".

To determine which expression represents gravity (g) in the formula for potential energy (P = mgh), we need to isolate g.

Let's look at each option:

1) p - m - h
This expression does not represent gravity (g), as it does not involve any multiplication or division.

2) p - mh
This expression does not represent gravity (g) either, as there is no division involved.

3) p / m0 - h
In this expression, the variable m0 is unrelated to gravity (g). Therefore, this option is not correct.

4) p / (mh)
This expression represents dividing potential energy (p) by the product of mass (m) and height (h). Therefore, this expression correctly represents gravity (g).

Thus, the correct expression that represents gravity (g) is option 4: p / (mh).
