How would you find the equation for the rate of change in volumes between two concentric spheres with progressing time given the radius as a function of time. I tried just subtracting the two volumes, but ofcourse thats wrong. In your answer please substitute the radius with r(t). Thanks.

No answers from the wiki. i don't really understand what it means. so the answer has got to be layman.

i understand that a superconductor has no resistance in it. it is a metal supercooled by liquid nitrogen and stuff. i just don't understand why the Meissner effect can make a magnet float.

I want to donate my body to science after I die and would like to know if there are any forms or places to contact to inform them of this? I have put this request in my will already. I don't plan on dying anytime soon but I would like to know this information but would like to know just in case something does happen in the near future.

Also, I would like to know if any body part remain will they be able to send them back to family to cremate?

Thanks

According to Einstein and others, gravity results from the curvature of space-time. It has been tested and is found true. I don't argue it. I just do not understand the following.

How does this explain my strong attraction to earth?

How can I understand that curvature of space-time is causing falling objects to accelerate at ca. 9.8 m/s^2 toward earth -- unfailingly?

It seems that for objects on earth something else is at work?

Is it love? (sorry for my fuzzy humor)

Any ideas? Any good explanations?
