Based on the emf value measured at frame 700, what is the average magnitude of the magnetic field inside the magnet assembly? Note that the loop has 10 turns; in other words, the total emf is the sum of the emf’s generated in each turn. In your calculations, use 26 mVmV for the magnitude of the total induced emf and 0.060 m/sm/s for the speed of the loop

Ibelieve the answer is d. macula  hope my answer has you : )

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.
