A firework display explodes high in the air. The resulting sound spreads out uniformly in all directions. The sound intensity level is measured to be 63 dB at a distance of 120 m from the explosion. What is the sound intensity at a location 120 m from the explosion

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.)
