Find the capacitance of a conducting sphere of 3cm in diameter, covered with a layer of polyethylene with& ,2.26 and 2 cm thick.

Newton's law of universal gravitation states that the force f between two masses, m1 and m2, is given below, where g is a constant and d is the distance between the masses. find an equation that gives an instantaneous rate of change of f with respect to d. (assume m1 and m2 represent moving points.)

Contrast the force of gravity between these pairs of objects a 1 kg mass and a 2 kg mass that are 1 m apart and two 2 kg masses that are 1 m apart

Which type of bond is found between the atoms of a molecule? a. metallic b. delocalized electron c. covalent d. ionic
