I don’t understand this Physics question and need help to study.

## Final Answer

Thank you for the opportunity to help you with your question!

The formula to calculate the emf E induced for a rod of length l moving at speed v perpendicular to the magnetic field B is E = Blv

We are using the vertical component of the magnetic field as it is this component of the field that the airplane is moving perpendicular to.

E = Blv = 5.1 x 10^(-6) x 39.9 x (860 x 1000/ 60 x 60) = 0.049 V (to 2 sig fig) = 49 mV (answer)

Please remember to convert the speed from km/h to m/s to ensure that you are working with SI units for all the quantities.

Please let me know if you need any clarification. I'm always happy to answer your questions.Brown University
