I have heard how math is related to MP3 compression format, anyone know more and would like to share his/her canny wit? -Tom

Would Someone check my work please? Here is the question. The pressure on 500g of copper is increased reversibly and isothermally from 0 to 5000atm. Where density = 8.96X10^3kg/m^3 Volume Expansivity = 49.5X10^-6K^-1 isothermal compressibility = 6.18X10^-12Pa^-1 specific heat = 385...

A block having a mass of 2.80 kg is given an initial velocity of 1.2m/s when it collides with a spring. The constant force of friction acts between the block and the surface with (mu sub k=0.5) and the force constant of the spring is k=100N/m. What is the maximum compression? I've been...

I am trying to figure out how many bricks can be stacked before the bottom brick is crushed? Not sure where to start - thinking about using bulk modulus for clay, but that only talks about compression, which I am sure there is a limit, but I am not sure how to find this. Thanks Nautica

Hello forum members I need some help on H.W problem...just enough reasoning to atleast get started the question is as follows: 5 moles of a monoatomic ideal gas at an initial volume of .50 m^3 and an initial pressure of 2.0 * 10^5 Pa undergoes an isothermal compression to .20m^3. Find...

"compression" of an electrostatic charged sphere Everytime i propose a new motion machine from my ignorance or misunderstunding of physics, your explanations solve some questions, but open new others: I proposed a system that acumulated electrons on a sphere surrounded by an electrons...

The other day i came across [Removed Broken Link], and while reading it i started thinking; "Why don't we human try to compress the things we learn before learning them, and uncompress them when we need to remember them ?". Then i realized that the human brain finds it easier to memorize a...
