Is it the 3rd law
What the laws which we declared as universal are not applicable at all the portions of the universe. With out knowing at least 1% about the universe, how we can declare a law as universal.
How many laws are applicable at the center of the black hole?
Is it a right think to use laser technology for removing space junk, what NASA is working right now.
(I think this will create severe problems in the future which we can sense)
Is the gravitational force zero at the center of the earth.
I think the Earth's gravitational force may become zero at that point. But the influence of sun, near by galaxies, universal gravitational constant will act on it. So the net gravitational force will not be zero at the center
I think their is no zero gravity point in the universe , because no body in the universe is stable and every body in the universe revolve around some other body weather it may be a small meteor to a large galaxy.
A
You can't even spot the presence of block hole at that point.
It seems to be like an empty space at that point in the nebula
U know that light cannot pass through the black hole, block whole even absorb the light passing near by it.
so
U can't see that part of the nebula and some part...
I did'nt get u correctly. wat my question is how long the electricity can be generated from a permanent magnet.
For suppose I am generating electricity from a permanent magnet by shaking(lenz's law). How long I can generate electricity by this process if I shake it for a life time
