Abob of mass m is suspended from a fixed point with a massless string of length l (i. e., it is a pendulum). you are to investigate the motion in which the string moves in a cone with half-angle θ. what tangential speed, v , must the bob have so that it moves in a horizontal circle with the string always making an angle θ from the vertical? express your answer in terms of some or all of the variables m, l, and θ, as well as the acceleration due to gravity g. v = lsin(θ) / sqrt(lcos(θ) / g)v = lsin(θ) / sqrt(lcos(θ) / g)

the independent variable, or the one that is intentionally manipulated is the speed.

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.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
