Two equally charged spheres of mass 1.00 g are placed 2.00 cm apart. when released, the initial acceleration of each sphere is 256 m/s2 . what is the magnitude of the charge on each sphere? you may assume that the only force acting on each sphere is the electric force due to the other sphere.

The sun generates both mechanical and electromagnetic waves. which statement about those wave is true?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

True or false graphs must include scales that increase by the same amount
