Two concentric conducting spherical shells each have a net charge of 1 C and all charges remain at rest. The charge on the outer surface of the outer shell is 1 C. The outer surface of the outer shell is at a potential of 2 V. The inner surface of the inner shell is at a potential of V.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
