a block rests on a horizontal surface the normal force is 20N and the coefficient of static friction between the Block and the surface is 0.40 and the coefficient dynamic friction is 0.20 what is the magnitude of the frictional force exerted on the Block what block is at the rest​

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?
