Astudent makes a simple pendulum by attaching a mass to the free end of a 1.50-meter length of string
suspended from the ceiling of her physics classroom. she pulls the mass up to her chin and releases it from
rest, allowing the pendulum to swing in its curved path. her classmates are surprised that the mass doesn’t
reach her chin on the return swing, even though she does not move. explain why the mass does not have
enough energy to return to its starting position and hit the girl on the chin.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
