Awheel on a game show is given an initial angular speed of 1.12 rad/s . it comes to rest after rotating through 0.75 of a turn.

part a. find the average torque exerted on the wheel given that it is a disk of radius 0.61 m and mass 5.4 kg.

part b. if the mass of the wheel is doubled and its radius is halved, will the angle through which it rotates before coming to rest increase, decrease, or stay the same?

(assume that the average torque exerted on the wheel is unchanged.)

will increase? will decrease? will stay same?

im sorry i dont know

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.
