Aboat leaves the dock at t = 0.00 s and, starting from rest, maintains a constant acceleration of (0.461 m/s2)i relative to the water. due to currents, however, the water itself is moving with a velocity of (0.485 m/s)i + (2.16 m/s)j. how fast is the boat moving, in m/s, at t = 4.82 s? how far, in meters, is the boat from the dock at t = 4.82 s?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
