At t=0t=0 a grinding wheel has an angular velocity of 27.0 rad/srad/s . It has a constant angular acceleration of 30.0 rad/s2rad/s2 until a circuit breaker trips at time ttt = 2.40 ss . From then on, it turns through an angle 438 radrad as it coasts to a stop at constant angular acceleration. Part APart complete Through what total angle did the wheel turn between t=0t=0 and the time it stopped? θθ = 589 radrad SubmitPrevious Answers Correct Part B At what time did it stop? tt = 12.5 ss SubmitPrevious AnswersRequest Answer Incorrect; Try Again; 3 attempts remaining Part C What was its acceleration as it slowed down?

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.
