Water flows through turbines in dams like the one shown below. The flowing water makes the turbines spin. What type of energy is used to make the turbines spin in this type of dam?

• Light energy

• Sound energy

• Thermal energy

• Mechanical energy

What needs to be done to this circuit so that the lamp lights up?

• Close the switch

• Add another lamp

• Add a power source and close the switch

• Add another lamp and a switch

The diagram shows a complete circuit but the bulb did not light up. Why?

• The plastic spoon is an insulator of electricity and prevented electric current from flowing through the circuit.

• The plastic spoon is a conductor of electricity and prevented electric current from flowing through the circuit.

• The plastic spoon is not connected properly and prevented electric current from flowing through the circuit.
