Angular momentum of a rotating string. equation (8.51) tells us that the momentum dp carried by given by a small piece of string is tods dp= c2 use this result to calculate by direct integration the angular momentum j carried by that your result coincides with (8.75) rotating open string. make sure 1 ε. 2π τος j = (8.75)

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
