Question

A given arteriole has a resistance of 4 . What would the new resistance of this vessel be if it's radius were to double ?


plz tell me answer with solution​

Answer 1

Answer:

The new resistance will be reduced to one fourth of original

Explanation:

it is known that:

  R=resistivity * Length/area

Area=pi r^2

resistance is inversely related to the square of the radius

if radius is double so resistance is reduced to one fourth of the original value

Original value is 4 so after doubling the radius it becomes 1

hope it will help you
