When light strikes a plane mirror

• it forms a virtual, upright image with magnification = 1
• it forms a virtual, upright image with magnification < 1
• it forms a real, upright image with magnification = 1
• it forms a virtual, inverted image with magnification = 1

The definition of electric current

• the rate of flow of charge
• the rise of charge per unit 
• the energy per unit time
• the amount of resistance over time

The formula that relates resistance in circuits to voltage and current

• R= V/I
• V+R=I
• I-R-V=0
• V=I/R

The graph shows an object that is

• maintaining a constant speed
• accelerating
• decelerating
• stopped

The voltage in a series circuit is 

• divided between components
• equal across all components
• equal to zero
• flowing through cells from negative to positive

Electric current in parallel circuits will

• divide at the junctions and then combine to return to the battery
• remain the same everywhere in the circuit
• add to the voltage
• subtract from the resistance
