Answer:

And since there is a frictional force acting upon the rotating blades of the fan due to the air, the speed of the fan blades ceases and ultimately comes to halt.

Can someone please help me with this? I would appreciate it.
Luba_88 [7]

Answer: State

Explanation:

The rock on the left is more shiny than the right, so that’s incorrect.

The rocks are not the same color, so that’s also incorrect.

Even though you can’t feel the textures, the right rock looks grainy and the left on doesn’t.

They both are solid, so that is the correct answer.
