Apassenger walks from one side of a ferry to the other as it approaches a dock. passenger's velocity is 1.55 m/s due north relative to the ferry, and 4.50 m/s at an angle of 30.0° west of north relative to the water. (a)what is the magnitude of the ferry's velocity relative to the water? (b) what is the direction of the ferry's velocity relative to the water?

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?
