The focal length of a lens needed by a woman whose near point is 50cm from her eyes is 50cm.
To find the answer, we have to know about the focal length of correcting lens.
<h3>
How to find the focal length of
correcting lens?</h3>
- If x is the distance of nearest point of the defective eye and D is the least distance of distinct vision, then, the expression for focal length of the correcting lens will be,
- It is given that, the woman whose near point is 50cm from her eyes, assuming the least distance of distinct vision for a normal eye is 25cm. Thus, the focal length will be,
Thus, we can conclude that, the focal length of a lens needed by a woman whose near point is 50cm from her eyes is 50cm.

Answer: The correct answer is "True".
Explanation:
Nephron is a functional unit of kidney. Each kidney contains a millions of nephrons. It contains small blood vessels.
It filters the blood to remove excess water and the waste product from the blood. Then, it returns the cleaned blood back to rest of the body. It selectively reabsorbs the substance such as glucose. It excretes nitrogenous waste such as urea. It removes excess salt in the form of urine.
Therefore, the given statement is true.

Explanation:
hydrostatic pressure, P=hρg,
where 'h' is the ht of the liq column and ρ is the density of the liquid and 'g' is the effective acceleration, but as far as hydroSTATICS is concerned, g stands for the acceleration due to gravity
