The study of the living and non living things in a environment is

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.)

True or false: the revolution of the earth creates day and night as it rotates around the sun

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.
