Imagine Sun and the Earth. Sun's gravity attracts the Earth. Now imagine some "superbeng," who quickly moves the Sun farther away from the Earth. What happens? We on Earth would feel...
a. stronger sun's gravity right away
b. weaker sun's gravity right away
c. stronger sun's gravity after some time
d. weaker sun's gravity after some time
question was typed word for word
if you can also tell me the rationalle that would be super
(PS, I know my avatar is ugly, but please answser the question anyway)
thanks

You're avatar IS ugly. don't listen to the person who said we didn't notice.
second, you've already gotten the weaker/stronger answer but nobody's given you the immediate/delayed answer. Gravity traveles at the speed of light. It takes light a few minutes to reach earth from the sun. That should give you the answer.

Since gravity is directly releated to distance, b. Assuming that we would not be killed instantly by the force that moved the sun in the first place. The energy or gravity required to do this would be enormous and would likely have a more instantaeous effect than the movement of the sun.
Actually, after some thought, we would not feel anything as the sun does not exert a noticeable gravity on us.

If the Sun is attracting the Earth, and all the sudden the Sun moves away from the Earth, what would happen to the gravity? Would it become stronger or weaker? Think about it this way: if I've got two magnets really close to each other, and they're trying to stick together, what happens when I pull them apart? What happens to the attraction between them? Does it get harder to pull them apart, or as they get farther away from each other, does the attraction seem to weaken?

this question is ez if u know physics
to calculate gravitational pull, u multiply the gravitational constant by the 2 masses dividied by the distance squared.
since the sun is moving further away, its obvious that the sun's gravity towards earth is going to be weaker
and since gravity is always there...if the distance is changed, the gravitational pull will change right away as well. It does not take time for gravity because it does not have to wait for anything, nor is there anything stopping it.

b. is correct. Gravity is determined by mass and distance. If the Sun is farther away, it's gravity upon Earth is less. If it moves away quickly, gravity weakens immediately.

it would depend on how fast the sun moved. if it moved slow then the gravity would get weaker slow and if the sun moved fast then the gravity would get weaker fast. so you would ahve to use logic on this question cause the answer is in the question...

since nobody ever measured the speed of gravity or defined it as electromagnetic or anything, the answer is B
