The diagram below shows a stationary cart on a frictionless surface. Two unequal opposing forces are about to be applied to the cart. If the unequal opposing forces are applied to the cart at the same time, what will occur?

The cart will remain stationary.

The cart will move to the left.

The cart will move to the right.

The cart will alternate between moving left and right.

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

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?
