A 1 F capacitor is connected to an emf that is increasing uniformly with time at a rate of 10 V/s. The displacement current between the plates is:

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

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.
