Iodine is the answer to your question buddy
Answer:
a)
4 times
b)
2 times
c)
0.5 times
d)
0.25 times
Explanation:
= Applied force by the person = F
= distance from the hinge = R
Torque is given as

(a)
= Applied force by the person = 2F
= distance from the hinge = 2R
New Torque is given as

So Torque becomes 4 times
b)
= Applied force by the person = F
= distance from the hinge = 2R
New Torque is given as

So Torque becomes 2 times
c)
= Applied force by the person = (0.5)F
= distance from the hinge = R
New Torque is given as

So Torque becomes 0.5 times
d)
= Applied force by the person = (0.5)F
= distance from the hinge = (0.5)R
New Torque is given as

So Torque becomes 0.25 times
Answer:
e. Only the rocket's motion from the top of its flight path until just before landing is free-fall.
Explanation:
A free-fall is a fall just under force of gravity. The rocket;s upward motion is result of engine push - even if it was shut down - and rocket free of engine push effect when it reaches it's maximum height after shutting down of engine. Then rockets stops at it's maximum height for a moment and rtuens back as free fall with only force of gravitation pulling it back to ground with acceleration 'g'.
Answer:

Explanation:
Initially rod is bent into L shaped at mid point
So we will have rotational inertia of the rod given as


Now when rod becomes straight during the rotation
then we will have

now from angular momentum conservation we have
