2. A closed cylinder with radius r= 12 cm lies with its longest axis parallel to the x-axis, and within an electric field E= 3x104 N/C that is also directed parallel to the x-axis as shown
in the figure. Calculate the electric flux:

a) On the circular base of the cylinder

b) On the entire cylinder.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

Which of the following list the divisions of the geologic time scale in order from longest to shortest
