**1) **Through how many degrees does a wheel rotate in 10 ms if its angular velocity is 8 rad/s???

You basically just need to know how to convert between angles and radians, and between seconds and milliseconds.

1000 milliseconds = 1 second

180 degrees = pi radians.

So 10 milliseconds, that's the same as 1/100 of a second, so we're talking about 8/100 = 0.08 radians. Now convert that to degrees.
