Answer:
The the angle between the axis of polarization of the light and the transmission axis of the analyzer is 52⁰.
Explanation:
Given;
I₀ as incident light intensity
The intensity of a linearly polarized light passing through a polarizer is given by Malus' law:
I = I₀Cos²θ
where;
I is the intensity after passing through the analyzer
θ is the the angle between the axis of polarization of the light and the transmission axis of the analyzer.
If 38% of the total intensity is transmitted, then I = 38% of I₀ = 0.38I₀
0.38I₀ = I₀Cos²θ
0.38 = Cos²θ
Cosθ = √0.38
Cosθ = 0.6164
θ = Cos⁻¹ (0.6164)
θ = 51.95° = 52⁰
Therefore, the angle between the axis of polarization of the light and the transmission axis of the analyzer to allow 38% of the total intensity to be transmitted is 52⁰.
Answer:
(a). The net gravitational force is 
(b). The position is at 0.232 m.
Explanation:
Given that,
Mass of one object M = 255 kg
Mass of another object M'= 555 kg
Separation = 0.390 m
(a). We need to calculate the net gravitational force
Using formula of force


Put the value into the formula


The net gravitational force is 
(b). We need to calculate the position
Force from 555 mass = Force from 255 mass




The position is at 0.232 m.
Hence, (a). The net gravitational force is 
(b). The position is at 0.232 m.
