Answer:

Explanation:

If I be the intensity of original light , after first polarization , its intensity becomes I/2

After second polarization its intensity becomes I/2 X Cos²θ

where θ is the angle between the two polaroids

So I₁ = I/2 Cos²θ

I₁ / I =.5 X Cos²θ = 0.123

Cos²θ = 0.246

θ = 60 degree. Ans

2. An 873 kg dragster accelerates at a rate of 44.6 m/s during a race.
Ira Lisetskai [31]

Answer:

<h3>38,673.9N</h3>

Explanation:

According to newton's second law:

Force = mass * acceleration

Given

Mass = 873kg

acceleration = 44.66m/s²

Magnitude of the force is expressed as;

F = ma

F = 873 * 44.6

F = 38,673.9N

<em>Hence the magnitude of the net force exerted on the dragster during this time is 38,673.9N</em>
