Chapter 12, Problem 1VSC

To determine

To Find: The diameter of Aldebaran.

Represent all the objects shown in the figure using 1 to 10 billion scale, on which the Sun is about the size of a grapefruit.

Answer to Problem 1VSC

Solution: The diameter of star Aldebaran would be approximately $6metres$

Explanation of Solution

Introduction: Size of the giant star Aldebaran is $30$ times larger than the size of the Sun.

Given that size of Sun is about the size of a grapefruit.

Thus, size of Sun is in between $\text{0}\text{.1m}$ to $0.2\text{m}$ .

Also, we know that size of star Aldebaran is $30$ times larger than the size of the Sun.

Thus, the size of star Aldebaran would range from $\text{3}\text{m}$ to $\text{6}\text{m}$ .

Hence, the diameter of star Aldebaran is approximately $\text{6}\text{m}$ .

Conclusion: Hence, diameter of star Aldebaran would be approximately $\text{6 m}$ .
