Experiments show that the ground spider uses one of its several pairs of eyes as a polarization detector. In fact, the two eyes
irina [24]

Answer:

The angle between the polarization direction of the eye and the polarization direction of the incident light = 56.1°

Explanation:

For polarization, the relationship between the intensity of transmitted rays (I), intensity of incident rays (I₀) and the angle between the polarization direction of the eye and the polarization direction of the incident light (θ) is given as

I = I₀ cos²θ

I = intensity of transmitted rays = 263 W/m²

I₀ = intensity of incident rays = 845 W/m²

θ = ?

263 = 845 cos²θ

cos²θ = (263/845) = 0.3112

Cos θ = √0.3112 = 0.5579

θ = cos⁻¹ (0.5579)

θ = 56.1°

Hope this Helps!!!

The dimensional formula of√(energy/) √mass is same as that of __________.
11Alexandr11 [23.1K]

Answer:

<em>D. Velocity</em>

Explanation:

<u>Energy Dimensional Analysis</u>

The kinetic energy (K) can be calculated by the formula:

\displaystyle K=\frac{1}{2}mv^2

Where:

m = mass of the object

v = speed at which the object moves

Solving for v:

\displaystyle v=\sqrt{\frac{2E}{m}}

Or, equivalently:

\displaystyle v=\frac{\sqrt{2E}}{\sqrt{m}}}

In dimensional terms, the quotient of the square roots of the energy and the mass is equivalent to the dimensions of the velocity (or speed),
