What did classical physics predict would happen to the light given off by an object as its temperature increased? O A. The color of the light would change to white, and the brightness would decrease.
O B. The energy of the light would increase from visible light into the infrared range
O C. The energy of the light would increase from visible light into the ultraviolet range.
○ D. The color of the light would not change, but the brightness would increase.

If a balloon is taken outside on a very cold day, what will occur?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?
