Astring under a tension of 56.9 n is used to whirl a rock in a horizontal circle of radius 2.55 m at a speed of 19.5 m/s. the string is pulled in and the speed of the rock increases. when the string is 1.18 m long and the speed of the rock is 52.5 m/s, the string breaks. what is the breaking strength (in newtons) of the string?

are you like autistic or something?

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

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.

not copied too! hope this !
