The large blade of a helicopter is rotating in a horizontal circle. the length of the blade is 7.26 m, measured from its tip to the center of the circle. find the ratio of the centripetal acceleration at the end of the blade to that which exists at a point located 4.35 m from the center of the circle.
Answers: 2
. If 
is the distance from the center of the point at the tip of the blade and 
is the distance from the center of another point in the blade, and since both points are rotating at the same angular velocity 
because both of them belong to the blade, the ratio between their centripetal accelerations will be:

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?
