Answer:
The intensity of light passing from the third polarizer is 3Io/16.
Explanation:
The law of Malus is given by

Let the incident intensity of light is Io.
The intensity of light passing from the first polarizer is

The intensity of light passing from the second polarizer is

The intensity of light passing from the third polarizer is

The answer is B- the process of cells making new cells
Answer:
The acceleration of the object is
.
Explanation:
Given that,
Mass of the block, m = 2.6 kg
Spring constant of the spring, k = 126 N/m
At the instant when the displacement of the spring from its unstained length is 0.115 m. We need to find the acceleration of the object.
When the block is displaced, the force acting on the spring is equal to the force due to its motion. Such as :

a is acceleration of the object

So, the acceleration of the object is
.
