(d) Boyle's law.

To determine

The correct option for the statement “The flight of a blimp best illustrates".

Answer to Problem 9RAT

The correct option for the statement “The flight of a blimp best illustrates" is option (a).

Explanation of Solution

A flight of a blimp controls its buoyancy in the air. It best illustrates the Archimedes principle.

The blimp controls its buoyancy in the air. The ballonets act like ballast and hold heavy air. These use a bag that helps to displace a large volume of air. The bag generally includes lightweight gases such as helium and hydrogen. The lightweight gas helium gives the buoyancy to the aircraft in the air. As the blimp rises, the outside air pressure decreases and helium in the envelope expands. The concept of the Archimedes principle is used in the flight of a blimp.

Conclusion:

Therefore, the correct option for the statement “The flight of a blimp best illustrates" is option (a).
