(This is from experience so sorry if it's wrong but) When wind instruments are played, sometimes the notes go flat or sharp depending on the speed the player blows air into the instrument as well as the warmth of the air. When playing a string instrument, the pitch can be changed in many ways. For example, when the player places their fingers on the string depending on which part of the tip of the finger you use, the tone of the sound and sometimes the pitch, changes. Looking at the question in a different way, you can change the pitch and the range of notes you can reach on the instrument (both wind and string) by changing the note you tune your instrument to. Hope this helps!!

The gravitational field intensity (EG) or (g) is the force on a unit mass at a point in the field.
Since the force (F) on a body of mass m in a gravitational field of a body of mass M = GMm/r2 .
you can see that the force per unit mass is given by F/m. So:
Gravitational Field Intensity (EG) = (g) = F/m = GM/r2
The units for EG are N kg -1 or since F = ma, F/m = a and so EG may be expressed in ms -2
Hope this will help you :))
Do give this answer a brainliest :D

Fluid always flow from higher pressure to lower pressure so as we can see the figure liquid is coming out of the spray bottle so it clearly shows that the pressure outside the tube will be lower than the pressure inside the tube.

Momentum is defined as product of mass and its velocity
