A physics student pulls a 100.0 kg chunk of stone with constant velocity of 0.50 m/a on a horizontal surface with a horizontal force of Fa=200.0N. If the rope breaks, how long does it take for the stone to come to 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?

Which model displays the change in a gas when the temperature of the gaseous system decreases?

The electric field inside a cell membrane is 8.0mn/c. what's the force on a singly charged ion in this field?
