Two planets have equal masses, are 1.0*1010 m apart, and have a gravitational force of 0.5 N towards each other. What are their masses?

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Which bonds are found inside a water molecule

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
