Answer:
Explanation:
The intensity of polarised light after polarization through angle θ
I = I₀ cos²θ
Here θ = 23 for first polariser
Intensity after first polarisation
= I₀ cos²23 = .846 I₀
For second polariser θ = 90 - 23 = 67 degree
Intensity after second polarisation
= .846 I₀ cos²67 = .13 I₀ .
Answer:
Here is the answer.
Explanation:
Balanced forces- they are those forces that produce 0 resultant forces.
therefore, on applying a balanced force on the object, it wouldn't result in any change, as resultant force would be 0.
Yes, that’s physically inactive. You should be moving your arms and legs if you’re going to be sitting down.
