Answer:
the kinetic energy lost due to friction is 22.5 J
Explanation:
Given;
mass of the block, m = 0.2 kg
initial velocity of the block, u = 25 m/s
final velocity of the block, v = 20 m/s
The kinetic energy lost due to friction is calculated as;

Therefore, the kinetic energy lost due to friction is 22.5 J

The major glands of the endocrine system are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and the reproductive organs (ovaries and testes). The pancreas is also a part of this system; it has a role in hormone production as well as in digestion.
Answer:
1)
2)
3)
Explanation:
Since the given masses are completely in xy plane we have
Moment of inertia about x axis equals

Applying the values we get

Similarly
Moment of inertia about y axis equals

Applying the values we get

Now by theorem of perpendicular axis of moment of inertia we have

Appying values we get
