Answer:

The correct option is c. 75 for this question

Explanation:

The correct option is c. 75 for this question:

Let's see how.

Continuity Equation is given as:

AcVc = AaVa

Where,

Aa = Area of Aorta

Ac = Area of the capillary

Va = Fluid speed in Aorta

Vc = Fluid speed in Capillary

So,

Assuming the fluid is the ideal one/

$\pi$ /4 $Dc^{2}$ Vc= $\pi$ /4 $Da^{2}$ Va

$Dc^{2}$ Vc= $Da^{2}$ Va

Dc = Da x $\sqrt{\frac{Va}{Vc} }$

Dc = 2.5 cm x $\sqrt{\frac{60 cm}{0.07 cm } }$

Dc = 73.192 cm

Dc = 75 approximately

Hence, the diameter of the capillary = 75 cm approximately

To solve this problem we will apply the concepts related to the electric field. This is defined as the product between the angular frequency, the number of turns of the body (solenoid in this case) the magnetic field and the sine of the angular frequency and time. Mathematically this can be described as

$E = \omega NBA |sin \omega t|$
