Final answer:
The fan typically makes three revolutions during its stopping process.The correct answer is three (c).
Step-by-step explanation:
The question is asking about the number of revolutions a fan typically makes during its stopping process.
The correct answer is three (c).
This can be determined by considering the options provided and their corresponding speeds. When a fan slows down, it goes from a higher rotation speed to a lower rotation speed. Option c states that the fan will slow to 0.01 rev/s, which means it will make 0.01 revolutions per second. Given that the stopping process will take some time, it is reasonable to assume that the fan will make multiple revolutions before completely stopping. Therefore, the correct answer is three (c).
