The product of an object's rotational inertia and its rotational velocity is?
The object's angular momentum
Year the law of conservation was discovered?
There are many laws of conservation. Some of the better-known ones are the law of conservation of energy, of momentum, and of rotational momentum.There are many laws of conservation.

If the torque of the rotational motion be zero then the constant quantity will be?
angular momentum
What would it take for earth to reverse its spin?
A great force would be required. - Among other things, there is a law of conservation of rotational momentum. This means that rotational momentum would have to be transferred somewhere else for this to happen.
Why do pulsars spin so fast?
Because of the conservation of rotational momentum. As a stars core collapses, it retains the original rotational velocity. As a pulsar or neutron star's original size was in the region of 60,000 time greater that it's current form, the rotational speed is multiplied by this factor. Maintaining the rotational momentum requires the star to spin faster.

When the rotational speed of a rotating system doubles its angular momentum?
Gets doubled
Why is a nebula rotating?
Because the star that blew it off of itself was rotating. Conservation of rotational momentum.
How is the moon able to rotate?
Everything in the universe (including the moon) has rotational momentum, causing rotation.
Which of the folloing are vector quantities?
You forgot to include the list, but typical vector quantities include position, velocity, acceleration, force, torque, momentum, rotational momentum.
When the net torque acting on an object is zero the object is in?
In that case, the object's rotational momentum won't change.
What will happen to the speed of a cue ball if all of its momentum were transferred to other billiard balls when playing pool?
If no rotational momentum is present as well, only a tiny fraction of which can be transferred to another billiard ball, the cue ball will stop. If rotational momentum is present, which is a part of cue ball control, the cue ball will roll in a direction dependent upon angle of contact and direction of rotation.
