He electric field between the plates of a parallel-plate capacitor is horizontal, uniform, and has a magnitude E. Asmall object with a charge of -2.17 μC is attached to the string. The tension in the string is 0.480 N , and the angle it makes with the vertical is 16 ∘. What is the magnitude of the electric field?

The density of a liquid could be found by using

An object starts from rest at point f and speeds up continuously as it moves around an oval. a. choose a point about 1/8 th of the way around the oval from point f, and label it point g. draw a vector to represent the velocity of the object at point g. b. determine the change in velocity vector   between points f and g.

The radius of a sphere is increasing at a rate of 9 cm/ sec. find the radius of the sphere when the volume and the radius of the sphere are increasing at the same numerical rate.
