Answer:
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.
Answer:
d
Explanation:
i think it is rotational inertia
because analogue of mass in rotational motion is moment of inertia. It plays the same role as mass plays in transnational motion.
hope it's right & helps !!!!!!!!!

Answer:
11.27N
Explanation:
Given parameters:
Mass of the book = 1.15kg
Unknown:
Magnitude of the normal force = ?
Solution:
The normal force is the vertical force exerted by a body on an object.
It can be described as the weight of an object.
Normal force = mass x acceleration due to gravity
Normal force = 1.15 x 9.8 = 11.27N
