This is exactly like your question 2. You need only substitute the given numbers here.
Givens
- N = 100 turns
- delta B = 0.25
- r = 0.04
- Area = pi * r^2 = 3.14 * 0.04^2 = 5.02 * 10^-3
- Cos 60 = 1/2 = 0.5
Formula
e = N * delta B * Area * cos phi
Solution
e = - 100 * 0.25 * 5.02 * 10^-3 * 0.5
e = 0.0628 = 0.063
Answer
A

This is a notes question. The result is a sine curve. I don't know how they are counting the change in direction. Is a rising curve different from a falling curve? For sure going from plus to minus is a change in direction, but I still don't know how to count it. It will depend on what you have been told.
I would answer 4 but this is by no means certain. The only other possible answer is 2
