Explanation:
Given that,
Displacement in ice block, 
Force exerted by water, 
To find,
Work done by the force during the displacement.
Solve,
We know that the product of force and displacement is called work done. It is also equal to the dot product of force and displacement as :


We know that, i.i = j.j = k.k = 1

So, the work done by the force on the block during the displacement is 4181 Joules.
i think the data is not complete but that's according to me
Explanation/Answer:
Wind turbines are more likely to be found near rural communities due to the large requirement for space.
25/1500 is equal to 0.8/x
0.8*1500 is equal to 1200
1200/25 is equal to 48 N
