In materials of the same phase, or state of matter, the speed of sound tends to decrease as the density increases. Is this true or false and why?

False because the molecules of a denser substance have less inertia and move very quickly as compared to molecules of a less dense substance.

True because the molecules of a denser substance have less inertia and do not move as quickly as molecules of a less dense substance.

False because the molecules in all substances have no inertia so it does not have any effect.

True because the molecules of a denser substance have greater inertia and do not move as quickly as molecules of a less dense substance.

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a

Determine the time it takes for a satellite to orbit the earth in a circular "near-earth" orbit. the definition of "near-earth" orbit is one which is at a height above the surface of the earth which is small compared to the radius of the earth, so that you may take the acceleration due to gravity as essentially the same as that on the surface. does your result depend on the mass of the satellite?
