Awheel released from rest is rotating with constant angular acceleration of 3.0 rad/s a) (4 points) after 6.5 s, what is its angular velocity? b) (4 points) through what angle has the wheel turned? (4 points) how many revolutions has it made? c) (4 points) what is the speed of a point 1.0 m from the axis of rotation? d) (4 points) what is the magnitude of the total acceleration of the same point?

answer; ///i do believe that the correct answer is ; ///(physical change);

c)as speed changes, wavelength and frequency change.

everything changes!

where are the vectors ?

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.
