Design a "bungee jump" apparatus for adults. a bungee jumper falls from a high platform with two elastic cords tied to the ankles. the jumper falls freely for a while, with the cords slack. then the jumper falls an additional distance with the cords increasingly tense. assume that you have cords that are 12 m long, and that the cords stretch in the jump an additional 19 m for a jumper whose mass is 120 kg, the heaviest adult you will allow to use your bungee jump (heavier customers would hit the ground).

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.
