A 3rd harmonic of a tube open at both ends will have displacement antinodes at both ends.
In a tube of length L with two open ends, the longest standing wave has displacement antinodes (pressure nodes) at both ends. The fundamental or first harmonic is what it is known as. The second harmonic is the longest standing wave in a tube of length L with two open ends.

Answer:
A compass works by detecting and responding to the Earth's natural magnetic fields. The Earth has an iron core that is part liquid and part solid crystal, due to gravitational pressure. It is believed that movement in the liquid outer core is what produces the Earth's magnetic field.
Explanation:
<span>Here, g is the acceleration due to gravity at the Earth's surface and is the standard gravity, defined as 9.8m/s....So, the force by that gravity is called g-force.....</span>
False. A sound wave is an example of a mechanical wave, not an EM wave.
Hope this helps! :)
