Suppose the magnitude of the proton charge differs from the magnitude of the electron charge by a mere 1 part in 109part awhat would be the force between two 1.9-mm-diameter copper spheres 1.4cm apart? assume that each copper atom has an equal number of electrons and protons. part bwould this amount of force be detectable? a. yesb. no

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
