1. A 5kg block, resting on a rough horizontal
Surface is connected by light in extensible String over a light friction less pulley to a
second block of mass 3kg hanging vertically.
An applied force of f acting on the
5 kg block is 24 N and
the coefficient of kinetic friction
between the 5kg and the surface is 0.2 . The 5kg block accelerates to the left.

a) Calculate the acceleration of the blooks.
b) Calculate the tension T​

this could be newton#'s law of cooling. the cooling curve is exponential

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.
