A 45 kg rock started rolling from rest to a final velocity of 8.3 m/s in 3.6 seconds. What is the force of the rock? [Hint: Calculate the acceleration first by using the equation a= (V, - V)/t]

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the

the answer is b

explanation:

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 !
