A cylindrical coil of radius 6 cm is placed in magnetic field, which is changing in time with the rate 0.5 T/s. The magnetic field direction is parallel to the cylinder axis. What should be the number of turns in the coil to induce the emf

Answer (d) valerie rides her bike south at 8 kilometers per hour///owen jogs south at 8 kilometers per hour ;
see the picture for the vector
the magnitude of the vector by pythagorean theorem
r = √( (-10)^2 + (3)^2 ) = √109
magnitude = √109 units
the direction angle between vector and x-axis is
tan^(-1)(3/10) = 16.699
so the direction is approximately 16.7 degrees north of west
induced emf value is missing..
please correct the question
