Homework Statement What is the ratio of the volume of the bulb of a thermometer to the volume of the thin tube in a bulb thermometer. It's not really a problem, but its just something I need to know to for my course. I can't find it anywhere else, so I was wondering if anyone knew it here...

Thanks Oh yeah, I forgot about that. I found out the compressibility of water (the bulk modulus) which was 0.21 *10 ^10 Pa. Using the equation delta(P)=-B*[delta(V)/V], where B was the bulk modulus and rearranging for delta(V) I got the right answer.

Homework Statement The deepest point in the ocean is in the Mariana Trench about 11 km deep. The pressure at the ocean floor is huge, about 1.13*10^8 Pa. a) calculate the change in volume of 1.00 m^3 of water carried from the surface to the bottom of the Pacific. b) The density of water at...

I have this problem for my AP Physics class that discusses the moon circling around the Earth. I am given the mass of the moon, time it takes for one revolution, and the moon's distance from the Earth (the radius of rotation). I am supposed to find out the tangential speed of the Moon traveling...
