An old movie poster used a quote "in space, no one can hear you scream! " why this is true or not true? a) the quote is incorrect, you can hear sound in outer space. reactivate b) sound cannot be polarized. so, you cannot hear sound in space. c) sound is an electromagnetic wave and needs no medium to travel through. reactivate d) sound needs a medium for the wave to vibrate and there is nothing in space to vibrate. i already know it is not a or c

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
