Determine the largest force p that can be applied to the 60-kg cart, without causing one of the wheel reactions, either at a or at b, to be zero. also, what is the acceleration of the cart? the mass center of the cart is at g.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

more than, less

less than, more

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.
