• expanding the flow of water in a pipe by making the pipe wider

• turning on a laser and reflecting the laser off of a mirror on the moon

When an electric circuit is "on" is the circuit open or closed?

• open

• closed

When an electric circuit is "off" is the circuit open or closed?

• open

• closed
