miv72 [106K]

The simple definition of work is the product of the force applied to the object and the displacement:

W = Fd

W is the work, F is the applied force, and d is the displacement.

Givens:

W = 5.0N-m

F = 25N (the applied force must be at least equal to the weight to lift it)

Plug in the given values and solve for d:

5.0 = 25d

d = 0.20m

Answer:

I didn't get pic from you but I got the type of answer that u want.

Explanation:

Water molecules are always moving. But on the average they are packed the same throughout. Therefore, the ratio between the mass and volume is the same, making the density the same. This is true no matter the size of the sample or where you select your sample from.
