a spherical Gaussian surface encloses a point charge q. if the point charge is moved from the center of the sphere to a point away from the center, does the electric field at a point on the surface change? does the total flux through the Gaussian surface changed?explain..

I have a question about impulse. So, impulse equals change in momentum or average force * change in time. So I have a couple of questions actually. Does impulse only apply for extremely small changes in time? Like if a car crashed and was in contact with something for a second before it stopped, is that still considered 'impulse'? Also, via the formula, the impulse becomes greater when the change in time becomes greater. But I thought there was a larger impulse when time was smaller? If anyone could help clear these up for me that would be great. Thanks :)

I know little of physics. Imagine if medical procedures once "invasive" due to cutting, like the retrieval of an organ, became less invasive because of a device that would allow the organ/body part to somehow pass through the skin unharmed. "Star Trek's" teleportation is fiction. What is a believable method? I read a little about "gravity waves", that they can pass through things unchanged, but I don't understand their application to the conversion of matter to energy in this situation. Could an organ be converted to a gravity wave, pass through skin, and then be usuable?
In Greg Iles "Footprints of God", the brain was scanned with an MRI and was uploaded to a computer, and the computer became the person. Replication/cloning leaves too much room for error. Could anything allow something to pass through the skin unchanged? Could a solid matter to energy conversion take place to allow an organ to pass through the skin, to then be converted back? What device(real or not) could do it?

I have been thinking about this recently and haven't really come up with a solid opinion on the matter.

Anyone have any ideas they would like to share with me?
Thanks

The black hole according to Einsteins theory of General relativity that says it to be an enormously powerful gravitational pull caused by a death stars extremely dense mass that warped space in to what it is identified as black hole. And nothing escapes this black holes when passing over it - even time will get slower.

I don't understand how he meant when he said " Time" becoming slower due to a gravitational effect.

I thought I remembered my physics of music class having something in it about how astronomers and philosophers used to also do a lot of studies on music and I thought Brahe was included in that group. I can't find anything online about him making contributions to scales or music or anything. Does anyone know what he did (not the astronomy part or the many myths)?

and by quantum theory it is also said that a photon also have particle nature .Then tell me that between the two orbits at what point the particle nature photon will emmit .If it emmit at the level of higher orbit then the e should come to lower one with infinit speed but it is not possible then if it emmit at the level of lower one but it seems foolish and continous desipation of energy is a classic idea.

A car is traveling at a constant speed of 30 m/s passes a highway patrol police car which is at rest. The police officer accelerates at a constant rate of 3.0 m/s^2 and maintains this rate of acceleration until he pulls next to the speeding car. Assume that the polic car starts to move at the moment the speeder passes his car. Determine the (a) time required for the police officer to catch the speeder and (b) distance traveled during the chase.

I tried using the equation deltat = (Vf-Vi)/a but, apparently, it's wrong...>.<
