HELP with this question.plzzz

The force on the cork is the weight of all the water that's directly over it. That's the water in a tall, skinny cylinder that's 2.0m long and has a base area of 2 cm^2.

Find the volume of that cylinder, use the density to find the mass of the water in that volume, then m•g to find the weight of that mass.

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.
