Answer:

The intensity of the light that passes through a polarizer is 0.55I₀.

Explanation:

The intensity of the light that passes through a polarizer can be found using Malus's law:  

I = I_{0}cos^{2}(\theta)

<u>Where</u>:

I: is the intensity of the light that passes through a polarizer

I₀: is the initial intensity

θ:  is the angle between the light's initial polarization direction and the axis of the polarizer = 42°  

I = I_{0}cos^{2}(\theta) = I_{0}cos^{2}(42) = 0.55*I_{0}

Therefore, the intensity of the light that passes through a polarizer is 0.55I₀.

I hope it helps you!

A dragster going at 15 m/s increases its velocity to 25 m/s in in 2 seconds. What is its acceleration?
Strike441 [17]

Answer:

5m/s²

Explanation:

Given parameters:

Initial velocity  = 15m/s

Final velocity  = 25m/s

Time taken  = 2s

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time taken. It is mathematically expressed as;

      Acceleration  = \frac{Final velocity  - Initial velocity }{Time taken }  

    Acceleration  = \frac{25  - 15}{2}   = 5m/s²
