Answer:
Explanation:
Let the intensity of unpolarised light be I₀ . After passing through the first polarising filter , the intensity is I₀ / 2 .
After second filter , the intensity will be I₀ / 2 x cos²45 = I₀ / 4
After third filter , the intensity will be I₀ / 4 x cos²45 = I₀ / 8 .
So,
1 / 8 the of initial light passes through the last filter .
Solution :
We know, resistance is given by :


Now, we know mass of wire is given by :

Hence, this is the required solution.
The worm is the invertebrate. All the other animals are vertebrates.
