Acutting tool under microprocessor control has several forces acting on it. one force is , a force in the negative y-direction whose magnitude depends on the position of the tool. the constant is α = 2.50 n/m³. consider the displacement of the tool from the origin to the point x= 3.05 m , y= 3.05 m . calculate the work done on the tool by if this displacement is along the straight line y = x that connects these two points.

what best describes physical development during adolescence is the development of secondary sex characteristics happens at a rate unique to each individual.

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.
