Question

Explain method for measurement of dimension of a planet or star according to standard 11th physics book.

Answer 1

Answer:

Explanation:

In day to day life, measurement of length is unavoidable. Small distances can be measured using the scale and expressed using a meter or foot. Large distances like the distance between two cities or two countries are measured using maps and electronic devices and expressed using kilometer or miles. Now, going a step ahead for measuring the distance between two stars, one needs efficient mathematical skills and techniques like – Triangulation and Parallax Method, and the obtained values are expressed in light-years or astronomical units.
