Time is precious, but we do not know yet how precious it really is. We will only know when we are no longer able to take advantage of itâ€¦iii)z varies directly as the square of x and inversely with the square root of y.. So22ykxzyxzï€½ïƒžï‚µExample 1The law of universal gravitation states that the gravitational force F (in newtons)between two objects varies jointly with their masses m1and m2(in kilograms) and inverselywith the square of the distance d (in meters)between the two objects. The constant ofvariation is denoted by G and is called theuniversal gravitational constant. Write anequation for the law of universal gravitationhence estimate the universal gravitationalconstant.
