Suppose you had a 100 gram mass and a 50 gram mass. Both masses appear to be made of the same material, but you can't be sure. You lower the 50 gram mass into a cylinder of water and the water goes from 30.3 mL up to 36.3 mL. The 100-gram mass is also placed in a cylinder of water and the water rises from 30.3 mL to 42.3 mL. Does the experiment provide evidence that the two masses could be made of the same material? Explain!

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.
