Anyways, applying the concept of Schwarzchild radius to an electron seems pointless.
EDIT: It appears it's not entirely pointless. There's even http://en.wikipedia.org/wiki/Black_hole_electron" [Broken]
1. "...in contact with an equal and opposite force" to what?
the object won't stop unless a there is a force that causes it to decelerate until it stops.
2. No, it will keep moving at a constant 100km/h.
Remember that acceleration involves work and energy, so nothing accelerates unless...
Consider 2 spacecraft isolated in space, with a mirror on their back, facing each other. One light pulse is shot between them. The photons reflect off the first one, transferring a momentum off 2p, travels in the opposite directions, reflects off the second spacecraft, giving it 2p...
Re: HELP!!! pounds to kcal
You are trying to add apples and oranges.
Kcal is a unit of energy, while pound is a unit of mass.
For determining how much weight in the long run a person will gain after consuming X kcal you would need precise data on his energy consumption.
Open system exchanges matter and energy with its surrounding.
Closed systems exchanges just energy with its surroudings; e.g a Thermos
An isolated system doesnt exchange anything with its surroundings. Its like if it were alone in the universe.
