Two point charges are enclosed by a spherical conducting shell that has an inner and outer radius of 13.0 and 15.2 cm, respectively. One point charge has a charge of q1=8.30 μC, while the second point charge has an unknown charge q2 . The conducting shell is known to have a net electric charge of −2.40 μC, but measurements find that the charge on the outer shell is + 3.70 μC. Determine the charge q2 of the second point charge.

heat the gas and measure the pressure

the answer is mosques. they are an important part of islamic culture.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
