A student attempts to measure the maximum possible distance two masses can be away from one another and still register on the force-meter available. The masses are 2 kg and 7 kg respectively while the force-meter is capable of detecting a force as low as 0.000002 N. What is the greatest distance the masses can be apart and still register on the force-meter

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?
