Two narrow slits 84 mum apart are illuminated with light of wavelength 650 nm. what is the angle of the m = 3 bright fringe in radians what is the angle in degrees

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

I’ve been stuck on this for a while

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
