5. A helicopter scoops a load of water out of a lake, to dump on a forest fire. The helicopter exerts 6480 N of force on the water while rising high enough to fly over a mountain. If the helicopter does 1.62 x
10%) of work on the water while lifting it, how high does it lift the water.

h = 250 m

Explanation:

Given that,

The helicopter exerts 6480  N of force on the water while rising high enough to fly over a mountain.

The helicopter does of work on the water lifting it.

We need to find how high does it lift the water. Work done is given by :

So, it can lift the water to a height of 250 m.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
