If the resistance of rheostat LL6 has been adjusted so that 30 mA flows through bulb H then what current flows through bulb B? What current flows through bulb C

10 is the . . .

Wish i knew this to !

The correct answer is c. hope this

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.
