Suppose that you want to move a heavy box with mass 30.0 kg across a carpeted floor. you try pushing hard on one of the edges, but the box does not move. suppose that you are pushing against the box from an angle 30.0∘ above horizontal with a force of magnitude 240 n. what is the magnitude of the friction force acting on the box?

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?

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?
