It is a well known fact that the ocean modifies the climate favorably so as to keep the ambient temperature warmer than it usually is inland away from the ocean so that is why the nightime drop in temperature will be less near the sea than inland.

Work is the force done to an object to bring about a displacement of the object.
when the block is being moved there are 2 forces acting on the block.
the force applied acts on the block in one direction bringing about its displacement in that direction. Theres another force called frictional force which acts against the movement of the block in the opposite direction to the direction in which the block is moving.
The resultant force acting on the block is ;
F = force applied - frictional force
frictional force - coefficient of friction *mg
mg - mass * gravitational acceleration
mg = 1 kg * 9.8 ms⁻²
= 9.8 N
frictional force = 0.5 * 9.8 N
= 4.9 N
resultant force = 20 N - 4.9 N
= 15.1 N
work done = force * distance moved
= 15.1 N * 3 m
= 45.3 J
