A saw rotating at 350 rad/sec is unplugged and the blade came to rest after rotating through 700 radians. a. What was the angular acceleration?
b. How long did it take the blade to stop?

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
