Answer:
35.1688 seconds
Explanation:
M = Mass of sphere = 8200 kg
R = Radius of sphere = 90 cm
F = Force = 30 N
Moment of inertia is given by

Torque is given by

For one rotation

The time taken to rotate the sphere from rest is 35.1688 seconds
Answer:
The diameter of a hydrogen atom based on scientific notation is 1.06 x 10^-10 m
Both bricks will hit the ground at the same time.
Falling vertically is always accelerating at 9.8 m/s² because of gravity.
Nothing that's happening horizontally has any effect on that.
The brick that happens to have some horizontal motion will
probably hit the ground way over there, but that will still be
at the same TIME as this one.
This is a perfect place to remind you of the old unbelievable story,
which I'll bet you heard before:
If you fire a bullet horizontally from a gun, and at the exact same
moment you DROP another bullet out of your hand next to the gun,
the two bullets will hit the ground at the same time ! Even though
they'll be far apart.
Horizontal speed has no effect on vertical behavior.
