Answer:
1 μC extra charge will be flow here
Explanation:
Given data
battery V1 = 4.0 V
flows Q1 = 6.0 μC
replace battery V2 = 7.0 V
to find out
what happen if we replace battery
solution
we apply here principal of capacitor
that is Q directly proportional voltage
so we say Q2/Q1 = V2/ V1
put all value here
Q2/Q1 = V2/ V1
Q2/6 = 7/ 6
Q2 = 7
so we see here 7 μC will be flow
and Q = Q2 - Q1 = 7 - 6 = 1 μC
so we also say that 1 μC extra charge will be flow here
Here is my step-by- step work! ( I know you did Step 3 for me or it was done in the problem, but I redid it anyway b/c I'm a nerd like that)
I got 79 meters for the answer.

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

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
17 Sin (45) in the vertical and 17 Cos
(45)
