Observe the image shown below. How is the energy from the solar panel allowing the traffic light to function?

• Light energy is absorbed by the solar panel. It is converted to electrical energy and is allowing the light to function

• Thermal energy is absorbed by the solar panel and converted to light energy

• Light energy is absorbed by the solar panel and converted to mechanical energy.

• Thermal energy is absorbed by the solar panel and converted to mechanical energy

A student builds a circuit made up of a battery, two light bulbs, and a switch. What will the student most likely observe in this circuit?

• Light bulb 1 and light bulb 2 will both be on

• Light bulb 1 will be off, but light bulb 2 will be on

• Light bulb 1 and light bulb 2 will both be off

• Light bulb 1 will be on, but light bulb 2 will be off

Which of these changes to the electric circuit shown above will cause the lightbulb to light up.

• Straightening the wire so that the current can flow more easily

• Adding a switch and more wire so that the current can flow more easily

• Turning one battery so that its positive end connects to the other battery's negative end

• Making the length of wire the same on both sides of the lightbulb
