The direction in which the potential changes at the greatest rate is in the direction The direction in which the potential changes at the greatest rate is in the direction of the partial derivative with respect to x. perpendicular to the gradient of the potential. of the gradient of the potential. perpendicular to the electric field. cannot be determined

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
