The mass of zorba, a mastiff born in london, england, was measured in 1989 to be 155 kg. this mass is roughly the equivalent of the combined masses of two average adult male mastiffs. suppose zorba is placed in a harness that is suspended from the ceiling by two cables that are at right angles to each other. if the tension in one cable is twice as large as the tension in the other cable, what are the magnitudes of the two tensions?

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.
