Answer:

Explanation:
From the question we are told that
Volume V
Contains N particles
Leaks from a small hole of area A
Generally the equation for Flow rate is given as
Volume Flow Rate 
Mathematically we find the time taken to flow half way which is given by

Therefore the time taken is

Answer:
L
Explanation:
For every action, there is an equal and opposite reaction.
As the moment of inertia if the gyroscope is 1/10 of that of the remainder of the satellite, the angular velocity of the satellite will be 1/10 that of the spun up gyroscope and in the opposite direction.
L = Iω
I'm pretty sure B would be your answer.
Force your doing it purposely and acceleration it’s just happening
