Answer:
You have no graph on the post.
600/3 = 200
the slope is 200m/min
OR
600/ (3/60) =
600 x 60/3 =
600 x 20 = 12,000 meters per hour
Answer:
The magnitude of average EMF induced in triangle is 0.0637
Explanation:
Induced EMF = (change in Magnetic Flux Density x Area)/change in Time
EMF = - ΔΦ /Δt

Exothermic because the heat make part of the result
