A cruise ship travels directly toward the dock with a velocity of 12 m/s relative to the water. A passenger walks 2 m/s in the same direction as the picture below shows. How far has the passenger walked relative to the dock after 3 seconds?

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
