I'm really struggling with these can i get some

1. a rubber rod can be charged negatively when it is rubbed with wool. what happens to the charge of the wool?

2. what is electrical power in terms of current and potential difference?

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
