Answer:
6.54 × 10⁻⁵ Pa-s
Explanation:
Since the shear force, F = μAu/y where μ = viscosity of fluid between plates, A = area of plates, u = velocity of fluid = 0.6 m/s and y = separation of plates = 0.02 mm = 2 × 10⁻⁵ m
Since F = μAu/y
F/A = μu/y where F/A = force per unit area
Since we are given force per unit area, F/A = 1.962 N per unit area = 1.962 N/m²
So, μ = F/A ÷ u/y
substituting the values of the variables into the equation, we have
μ = F/A ÷ u/y
μ = 1.962 N/m² ÷ 0.6 m/s/2 × 10⁻⁵ m
μ = 1.962 N/m² ÷ 0.3 × 10⁵ /s
μ = 6.54 × 10⁻⁵ Ns/m²
μ = 6.54 × 10⁻⁵ Pa-s

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

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
Answer:
Explanation:
We shall apply Gauss's Law to find the solution .
flux entering the cube = E X A
= 46.8 X 147.1 X 147.1 Weber
flux going out of cube
= 114 x 147.1 X 147.1 Weber
Net flux going out
= ( 114 x 147.1 X 147.1 - 46.8 X 147.1 X 147.1 )
= 1454101.15 weber .
according to Gauss's law
q / ε₀ = 1.4541 x 10⁶ , q is required charge inside the cube.
q = 8.85 x 10⁻¹² x 1.4541 x 10⁶
= 12.868 x 10⁻⁶ C
= 12.868 μC.
