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:
The four fundamental forces magnitude and range are in order of Strong Nuclear Force > electromagnetic force > weak nuclear force > gravitational force.
Explanation:
The 4 fundamental force are weak nuclear force, strong nuclear force, em force and the gravitational force are discussed below.
Strongest force is the strong nuclear force as compared to all of them. It is very useful for capturing the atoms nucleus together despite the large repulsion which is occur between the same charges due to protons in the nucleus.
Electromagnetic Force is the 2nd strongest fundamental force. Magnetism and electricity was thought to be of 2 separate forces.
Weak Nuclear Force involves the W and Z bosons exchange. It has a very short range of
Gravitational Force is the weakest between all the fundamental forces. However, due to its long range it is the most dominant force. It follows the inverse square law like but it is always attractive in nature.
Answer:
Units. Torque has the dimension of force times distance, symbolically T−2L2M. Although those fundamental dimensions are the same as that for energy or work, official SI literature suggests using the unit newton metre (N⋅m) and never the joule. The unit newton metre is properly denoted N⋅m.
Dimension: M L2T−2
In SI base units: kg⋅m2⋅s−2
Other units: pound-force-feet, lbf⋅inch, ozf⋅in
