With the aid of a string, a gyroscope is accelerated from rest to 32 rad/s in 0.40 s. (a) what is its angular acceleration in rad/s2? (b) how many revolutions does it go through in the process

Will you chech and finish these for me, because i am stumped with them.

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
