Answer :
Final answer:
The reduction in brake effectiveness due to increased temperature is known as brake fading, caused by the conversion of the car's motion energy into heat.so the correct option is (A).
Explanation:
As brakes heat up, you may experience a reduction in their effectiveness. This phenomenon is known as brake fading. When you step on the brakes, all the energy of the car's motion is converted into heat in the brake shoes. This heat can lead to an increase in temperature (ΔT) of the brake components which can cause the brakes to fade. The mechanical equivalent of heat is demonstrated when we see smoking brakes on a truck, an example of heat generated due to friction as the output piston squeezes the brake pad against the surface of the brake disc causing the vehicle to slow down or stop.
