Verified Answer :

using newton law 
d=W/F
d=10/10
d=1m
so the shelf is 1m high.

Answer:

A. 1 m

Explanation:

The work done to lift the box is equal to the product between the force applied and the distance covered by the box:

\(W=Fd\)

In this case, the force applied is equal to the weight of the box (F=10 N), and we know that the work done is W=10 J, so we can rearrange the formula to calculate the distance d:

\(d=\frac{W}{F}=\frac{10 J}{10 N}=1 m\)
