Suppose you exert a force of 180 N tangential to a 0.280-m-radius, 75.0-kg grindstone (a solid disk). (a)What torque is exerted

Explanation:

Torque is expressed according to the formula;

F is the force exerted

r is the radius

Given

F = 180N

r = 0.280m

Required

Torque

Substitute into the formula and get torque

Hence the torque exerted is 50.4Nm

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.
