What is the useful energy in a whistle?
The useful energy in a whistle is the sound energy produced when air is forced through a small opening, creating vibrations that travel as sound waves through the air. The pitch and volume of the sound are determined by the size and shape of the whistle.
How does a whistel work?
A whistle works by forcing air quickly through a narrow opening, creating high-pitched sound vibrations. The vibrations travel through the air as sound waves and produce the whistling noise that we hear. The shape and size of the whistle's chamber help amplify the sound.

How does a safety whistle work?
A safety whistle works by using the force of air blowing through it to create a high-pitched sound. When you blow into the whistle, the air passes through a small opening and causes a vibrating column of air inside the whistle. This vibration creates a loud, attention-grabbing sound that can travel over long distances to alert others of your location or in an emergency situation.
Truman was the first president to travel by what mode?

The path a sound waves travels before you hear a whistle being blown?
When a whistle is blown, sound waves are produced and travel through the air as longitudinal waves. The waves propagate through the air until they reach your ears, where they are detected by your ear drums and converted into electrical signals that are sent to your brain for processing. This process is almost instantaneous, allowing you to hear the whistle as soon as it is blown.
