Examine the electromagnetic spectrum below. Diagram of the electromagnetic spectrum. At the far left, the waves are very far apart, and at the far right, the waves are very close together. x-rays are farther to the right of the diagram than microwaves are. What can you conclude about x-rays compared to microwaves? X-rays have the same frequency as microwaves. X-rays have a lower frequency than microwaves. X-rays have a longer wavelength than microwaves. X-rays have a shorter wavelength than microwaves.

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?

This energy transformation diagram represents the energy of a skateboarder moving along a half-pipe. as she skates toward the top of the half-pipe, her original kinetic energy is converted to potential energy and friction. how much of the energy is potential?

The two stars in a certain binary star system move in circular orbits. the first star, alpha, has an orbital speed of 36 km/s. the second star, beta, has an orbital speed of 12 km/s. the orbital period is 137 d. a) what is the mass of the star alpha? b) what is the mass of the star beta?
