A disk with a hole has inner radius rin and outer radius rout. the disk is uniformly charged with total charge q. find an expression for the on-axis electric potential at distance z from the center of the disk

Two small, positively charged spheres have a combined charge of 5.20x10^-5 C. If each sphere is repelled from the other by an electrostatic force of 1.00 N when the spheres are 2.20 m apart, what is the charge on the sphere with the smaller charge?

Josh rolled a bowling ball down a lane in 2.5 seconds. The ball travelled at a constant acceleration of 1.8 m/s/s down the lane and was traveling at a speed of 7.6 m/s by the time it reached the pins at the end of the lane.

How many meters of the rock wall eroded between 1910 and 1927?

As air temperatures increase, evaporation increases. Warmer temperatures also increase the capacity to absorb water vapor. More water vapor in the atmosphere accelerates the greenhouse effect.
