Determine the magnitude of the magnetic flux through the south-facing window of a house in British Columbia, where Earth's B⃗ field has a magnitude of 5.8 × 10−5 T and the direction of B⃗ field is 72∘ below horizontal with the horizontal component of B⃗ field directed to the north. Assume the area of the window is 5.0 m2.
I am told 2.76*10^-4 T*m2 and 8.96*10^-5 T*m2 are incorrect answers.

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v
