A3.2-meter boom is acted on by the 3500-n force shown. determine the tension in each cable and the reaction at the ball-and-socket joint at a 2 m e 2m d 2.2 m a 12m 1.2 m 3500 n

the force required to move the cart is divided by three or 33.33 n.

change tension

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.
