Find speed of generator when it has 7.5kw, 20 Amps, B = 0.8w/m2, length = 150mm, diameter 200mm, there are 600 conductors at 65 % below the pole.

I just don't understand the 65% below the pole. Does it relate to phase angle or power factor somehow?
The boundary-value problem
y = 4(y − x), 0 ≤ x ≤ 1, y(0) = 0, y(1) = 2
has the solution y(x) = e^2(e4 − 1)−1(e^2x − e−^2x) + x. Use the Linear Finite-Difference method to
approximate the solution, and compare the results to the actual solution.

b. With h = 1/4.
