The gravitational constant may also be calculated by analyzing the motion of a rocket. suppose a rocket is launched vertically from the surface or earth at an initial speed of vi. its initial distance from the center of earth is ri, the radius of earth. its peak distance, where its speed is momentarily zero is, is rf. for simplicity, ignore air resistance and earth’s rotation. enter an expression for the gravitational constant, in terms of vi, ri, rf, and me.

Explanation:

As we know that during the projection of rocket the total mechanical energy is conserved as there is no friction in it's motion

So we will have

now divide whole equation by mass of the object

now we can rearrange above equation to find gravitational constant

So above is the expression for gravitational constant G

true is the correct answer

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 !
