Object a and object b are 10 m apart. which of the following will cause the greatest increase in gravitational force between the objects?
increase the mass of object a.
increase the mass of object b.
increase the distance between objects a and b.
increase the mass of both object a and object b.

As the gravitational force is calculated by gmm/r^2, the greater the masses, the greater the gravitational force between the two objects

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
