Imagine a balance whioh has identical sliding baskets on cach side of the fulcrum. One jimpsitontams-70 Big Maos from McDonalds, cach with a Mags of O P, sk%, The other baske
hardsti2 whoppers from Burger Kine, each with a mass of 0,40 K8; The basket containing
the Whoppers is placed 125 centimeters from the fulcrum. Where does the basket of Big
Macs need to be placed on the other side of the fulcrum to create a Net Torque of zero?
(meaning the balance will not rotate, it will be perfectly horizontal)

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

because if the tool that you are using is not balanced it there would be false mass.
