692. Which type of energy transformation occurs in an electric motor? A) Mechanical to electrical B) Electrical to mechanical C) Chemical to thermal D) Thermal to electrical
B) Electrical to mechanical Explanation: An electric motor converts electrical energy into mechanical energy, creating motion.

693. When turning a wheel and axle system, which component requires less force to move? A) Wheel B) Axle C) Both require the same force D) Neither
A) Wheel Explanation: Turning the wheel in a wheel and axle system requires less force than turning the axle, due to the larger radius of the wheel.

694. In a series circuit, if one light bulb burns out, what happens to the other bulbs? A) They burn brighter B) They stay the same C) They turn off D) They become dimmer
C) They turn off Explanation: In a series circuit, if one bulb goes out, it breaks the circuit, causing all bulbs to turn off.

695. Which of the following describes an inclined plane? A) A flat surface that reduces the effort needed to lift a load B) A rotating wheel that moves loads C) A rope that lifts loads D) A pointed tool that cuts material
A) A flat surface that reduces the effort needed to lift a load Explanation: An inclined plane is a flat, sloped surface that allows a load to be lifted with less force by increasing the distance.

696. Which of the following is true of a third-class lever? A) The load is between the fulcrum and the effort B) The effort is between the fulcrum and the load C) The fulcrum is between the load and the effort D) The fulcrum and load are the same
B) The effort is between the fulcrum and the load Explanation: In a third-class lever, the effort is applied between the fulcrum and the load, as seen in a fishing rod.

697. If a pulley system has a mechanical advantage of 4, how many sections of rope support the load? A) 1 B) 2 C) 3 D) 4
D) 4 Explanation: The mechanical advantage of a pulley system equals the number of rope sections supporting the load, so a mechanical advantage of 4 requires four rope sections.

698. The primary function of a turbine in a power plant is to ___. A) Store energy B) Convert mechanical energy to electrical energy C) Transfer heat energy D) Measure electrical current
B) Convert mechanical energy to electrical energy Explanation: Turbines in power plants convert the mechanical energy of spinning blades into electrical energy via a generator.

699. In an electric circuit, resistance is measured in ___. A) Volts B) Amps C) Ohms D) Joules
C) Ohms Explanation: Resistance in an electric circuit is measured in ohms (Ω), which quantifies how much the circuit resists current flow.

700. When an object is in freefall, the only force acting on it is ___. A) Friction B) Air resistance C) Gravity D) Inertia
C) Gravity Explanation: In freefall, gravity is the only force acting on an object, causing it to accelerate downward.
