A lamp in a circuit has a potential difference of 12 V across its terminals when the current
through the lamp is 2.0 A.

1) Calculate the charge flow through the lamp in 300 s.

2) Calculate the electrical energy supplied to the lamp in 300 s.

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.
