Suppose you have three objects of equal mass. the first object has a volume of 5 cm3 and is made of a material of density 2 g/cm3. the second object has a volume of 10 cm3 and is made of a material of density 1 g/cm3. what is the density rho of the material of the third object if its volume is 15 cm3?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
