Answer:
The angular velocity is
Explanation:
From the question we are told that
The mass of the child is 
The radius of the merry go round is 
The moment of inertia of the merry go round is 
The angular velocity of the merry-go round is 
The position of the child from the center of the merry-go-round is 
According to the law of angular momentum conservation
The initial angular momentum = final angular momentum
So

=> 
Now
is the initial moment of inertia of the system which is mathematically represented as

Where
is the initial moment of inertia of the boy which is mathematically evaluated as

substituting values


Thus
Thus


Now

Where
is the final moment of inertia of the boy which is mathematically evaluated as

substituting values


Thus


Thus

Hence

A
longitudinal wave is a mechanical wave that causes the medium to vibrate
parallel to the direction of the wave. Its wave’s forces travel through
multiple rarefactions and compressions where compression is the closest
distance in the longitudinal wave and rarefaction is the farthest distance
apart in the said wave.
Answer:
Yes, it could discern all of them.
Explanation:
A compound bright field microscope can be used to illuminate samples in light microscopes. It has a very high resolution and it could detect samples as small as 200 to 300 nanometers. So, yes it could discern two objects separated by 3μm, 0.3μm, 300nm,3000Å.
