How do the Soviets(Russians) fell on this issue.

i am doing a science fair project in where i find which liquid makes an egg float but i have to find the density of the liquid. i know that to find the density i have to divide the mass by the volume but i can't do it because i don't know how to find the volume. can you give me an example plz.

Question: A typical 12-V car battery can deliver about 7.5 x 10^5 C of charge before dying. This is not very much. To get a feel for this, calculate the maximum number of KILOGRAMS of water (100 deg celsius) that could be boiled into steam (100 deg celsius) using energy from this battery.

My Thoughts:
I know V = EPE/q is supposed to utilized in this problem. i tried to substitute some equations into the problem, but they don't seem to fit!! i want to get a mass amount...i just don't know how to do that. someone help me out by showing me how to do the problem! appreciate all the help i can get.

Book Answer: 4 kg (just for checking purposes!)

(i will award a best answer - i promise)

Methane gas, like helium, weighs less than air. When you let helium out of a balloon, it weighs more. Therefore, it seems reasonable that when a person "relieves" himself of excess gas (which is primarily lighter-than-air gases), he weighs more - if even only a small fraction of a pound.

please help ......i dont find the general solution.....itt is a linear differential equation

1. (y+1)dx + (4x-y)dy=0
2. udx + (1-3u)x du = 3udu
3. (y-x+xy cot x )dx +xdy = 0
4 .y' = csc x - ycot x

thanks for the help

A lot of the people asking questions in the mathematics section (as well as some others) are simply trying to get answers to their homework, hoping someone explains everything step by step and gives an exact answer so they can just copy it down. If we do that for people, aren't we just crippling their learning process? They won't learn the material, which is the main goal of their homework and their education. This can have negative effects on them, such as failing exams or even entire math classes because they don't understand the material - they never learned it. Think about it... aren't we just crippling them? Don't you think we should gladly provide assistance and try to teach them and help them learn instead of giving the answer flat out?
