to race their cars, the students follow the steps below.\n1. turn bottle cap 2 to twist the rubber band.\n2. place the car on the floor while holding the bottle cap in place.\n3. release the bottle cap so that the plastic fan spins and the car moves forward.\none of the toy cars travels faster and farther than the other toy car. which of the following best explains why this occurs?\na its wheels are larger and transfer more potential energy to the floor.\nb its rubber band is longer and stores more kinetic energy from the bottle cap.\nc its fan takes more time to spin and transfers more kinetic energy to the wheels.\nd its rubber band is twisted tighter and transfers more potential energy to the fan.

Answer

Brief Explanations:

The rubber - band stores elastic potential energy when twisted. A tighter - twisted rubber band has more elastic potential energy. When released, this potential energy is transferred to the fan as kinetic energy, making the car move faster and farther. Larger wheels don't transfer potential energy to the floor, a longer rubber band stores elastic (not kinetic) energy when twisted, and a fan taking more time to spin doesn't necessarily mean more kinetic energy is transferred to the wheels.

Answer:

D. Its rubber band is twisted tighter and transfers more potential energy to the fan.
