Answer:
Work done, W = 0
Explanation:
Given that, a container of water is lifted vertically 3.0 m then returned to its original position.The total weight of the container is 30 N. We need to find the total work done by the container. We know that the work done by an object is given by :
W = F × d
Where
F is the applied force
d is the displacement of the object
It is mentioned that the container returns to its original position, the displacement of the container is equal to 0. Hence, no work was done by the container of water.
it is from under the earth's surface. There are under the surface streams that create springs
It is precipitation that fell on the ground and seeped down to a layer of rock. The water comes from an aquifer that is under the ground.
