Answer quickly i'm doing the test in the following system, what is the clockwise torque? 150 nm1,200 nm2,400 nm4,800 nmquestion 2 (same image)which of the following is true about this system? it will rotate clockwise. it will rotate counterclockwise. it is balanced and will not rotate. question 3 (same image) in the following system, what is the counterclockwise torque? 150 nm1,200 nm2,400 nm4,800 nm

Part 1

Clockwise torque is due to force applied at right end

So we will have

Part b)

Since we can see that at both sides the applied force will exert same torque on the rod so it is in balanced condition

So the rod will not rotate and remains in equilibrium

It is balanced and will not rotate.

Part c)

Counterclockwise torque is given as

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
