A BLOCK OF MASS 500G IS PULLED FROM REST ON HORIZONTAL FRICTIONLESS BENCH BY STEADY FORCE F AND TRAVELS 8M IN 2S .FIND THE ACCELERATION. PLEASE ALSO GIVE ME EXPLAINATION

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.)

A150 w lamp emits light of wavelength 590 nm uniformly in all directions. what is the photon flux (photons per unit area per unit time) on a small screen at a distance 2.3 m from the lamp? assume the photons are uniformly distributed over the surface of a sphere of radius 2.3 m.

Debbie places two shopping carts in a cart corral she pushes the first cart which then pushes a second cart what force is being exerted
