A wheel, starting from rest, rotates with a constant angular acceleration of 1.20 rad/s2. During a certain 2.00 s interval, it turns through 4.60 rad. (a) How long had the wheel been turning before the start of the 2.00 s interval? (b) What was the angular velocity of the wheel at the start of the 2.00 s interval?

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
