If an air parcel is given a small push upward and it falls back to its original position, the atmosphere is said to be Stable.
A Stable atmospheric condition is a state where a body thrown like an parcel tends to return to its original position where it was present earlier even after being disturbed externally.
Stable conditions tends to oppose the forces that lead to the displacement of the object from original position.
When a parcel is given a small push upward and it falls back to its original position in air. This shows Stability in the atmosphere which bring back the sir parcel where it was present initially.
A body under the action of gravity in case of stable equilibrium conditions shows returning back of the body after sometime on reaching a certain height.

<span>In this demonstration, there is a single compass and a piece of wire that is perpendicular to the plane that the compass sits on. The wire with current flowing through it can alter the direction the compass needle points.</span>
Answer:
3100 m/s
Explanation:
The relationship between frequency and wavelength of a wave is given by the wave equation:
where
v is the speed of the wave
f is its frequency
is the wavelength
For the wave in this problem,
f = 15,500 Hz
Therefore, the wave speed is
It would be B, like charges repel and unlike charges attract.
