1. Air resistance force usually upwards, but gravity doenwards.
2. Objects are affected by gravity the same, but air resistance can affect the speed of an object's descent.
Sorry if im wrong
Answer:
The intensity is 
Explanation:
From the question we are told that
The intensity of the unpolarized light is 
The angle between the ideal polarizing sheet is 
Generally the intensity of light emerging from the first polarizer is mathematically represented as

substituting values


Then the intensity of incident light emerging from the second polarizer is mathematically represented by Malus law as

substituting values
![I_2 = 2000 * [cos (24.58)]^2](https://tex.z-dn.net/?f=I_2%20%20%3D%202000%20%20%2A%20%5Bcos%20%2824.58%29%5D%5E2)

We are given with the expression d = ut + 0.5 at^2 and is asked to express the equation in terms of a. First, we transpose ut to the left side, then we multiply to the equation and divide lastly the resulting equation by t^2. The final expression becomes a = 2(d-ut)/t^2.
