Answer and Explanation:
We have given the expression 
Dimension of 
Dimension of R which is gas constant
Dimension of temperature T 
And dimension of pressure 
Now combine dimension of 
So the dimension of and dimension P is same so there unit will also be same
From ideal gas equation we know that 
As the both P and has same dimension so they are dimensionally constant

Answer:
the last one
Explanation:
Because it is a magnifying glass, it magnifies the object and makes it bigger than it appears
Answer:
η = 1.31
Explanation:
The formula for the refractive index of from air to some other medium is given by the following formula:
where,
η = refractive index = ?
c = speed of light in air = 3 x 10⁸ m/s
v = speed of light in ice = 2.29 x 10⁸ m/s
Therefore, using these values in the equation we get:
<u>η = 1.31</u>
