Two 9.00 hc charged particles are located on the x axis. one is at x -1.00 m, and the other is at x -1.00 m. (a) determine the electric field on the y axis at y = 0.600 m n/ci+61286 n/c (b) calculate the ele ni+ ctric force on a 3.00 μc charge placed on the y axis at y = 0.600 m. need ? read it

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

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
