Chapter 2, Problem 108A

Interpretation Introduction

Interpretation:

The density of black hole is $4.5273\times {10}^{10}{\text{g/cm}}^{\text{3}}$ and that of water is $1{\text{g/cm}}^{\text{3}}$. Compare the densities of black hole and water.

Concept introduction:

Density of a sample of matter or an object is equal to the mass of the sample divided by the volume of the sample.

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Answer to Problem 108A

Density of black hole is $45$ million times greater than the density of water.

Explanation of Solution

As the density of black hole is $4.5273\times {10}^{10}{\text{g/cm}}^{\text{3}}$ which is much greater than the density of water whose density is. $1{\text{g/cm}}^{\text{3}}$. The density of black hole is $45$ million times greater than the density of water.

Conclusion

Density of black hole is $45$ million times greater than the density of water.
