A positively-charged balloon is brought near a neutral, conducting sphere (mounted on an insulating stand). The sphere is touched by a person and the balloon is moved away. Once the process is over, what is the charge on the metal sphere?

Negative

A small, permanent magnet is suspended by a spring balance above the center of a circular coil of wire that is sitting on a balance. A large current is now introduced into the coil, causing the magnet to be attracted to the coil.

Will the reading on the upper spring balance increase, decrease, or stay the same?

increase

Roughly where is the magnet when the light bulb is the brightest?

The light bulb is brightest when either end of the magnet is entering or exiting the coil.

Red

Which color in the electromagnetic spectrum has the highest frequency

Violet

Which color in the electromagnetic spectrum has shortest wavelength
