Explanation:
Roughly one out of every thousand stars that form is massive enough to become a black hole. Therefore, our galaxy must harbor some 100 million stellar-mass black holes. Most of these are invisible to us, and only about a dozen have been identified. The nearest one is some 1,600 lightyears from Earth.
Based on the calculations, the pressure inside this droplet is equal to 2,909.35 kPa.
<u>Given the following data:</u>
- Surface tension = 0.00518 lbf/ft to N/m = 0.00702 N/m.
- Atmospheric pressure = 14.7psia to kPa = 101.35 kPa.
- Diameter = 0.01 mm to m = 0.00001 m.
Radius, r = 
= 0.000005 m.
<h3>How to determine the pressure inside a droplet.</h3>
For a droplet with only one surface, its pressure is given by this formula:
Substituting the given parameters into the formula, we have;
Inside pressure = 2,909.35 kPa.
