A tube contains enclosed air by a thread of mercury of 250 mm long when tube is horizontal the length of air is 250 mm long what is the pressure on the air column when atmospheric pressure is 750 mmhg?
A tube contains enclosed air by a thread of mercury of 250mm long when tube is horizontal the length of air is 250 mm long. The pressure on the air column when atmospheric pressure is 750 mm Hg is 3 Pascal or 3 N / m2.
What is the effect of length of air wedge on bandwidth?
Well, friend, the length of an air wedge can affect the bandwidth by changing the interference pattern of light passing through it. A longer air wedge can create more interference fringes, resulting in a wider bandwidth. It's like painting a beautiful landscape - each element plays a part in creating the final masterpiece.
How does a panpipe produce sound?
each pipe is a different length.... the shorter the pipe the higher the note....the longer the pipe the lower the note...
A change in can bring about a change in air pressure?
if the dna sequence of a gene was tacttaccgagctagact then what kind of mutation has occured This has nothing to do with the question of air pressure. Either a change of temperature or a change of volume can affect air pressure, according to Boyle's Law of Gases. Increasing temperature=increased air pressure Decreased volume=increased air pressure The reverse is also true. Decreased temperature=decreased air pressure Increased volume=decreased air pressure
Name something that needs to travel slowly through air how does it manage this?
A skydiver - he uses a parachute that slows him down as a result of air resistance acting on the surface of the parachute

What is resonance air column?
A resonance air column refers to a column of air in which sound waves resonate or vibrate at specific frequencies. This phenomenon occurs in musical instruments like flutes and organ pipes, where the length of the air column determines the pitch of the sound produced. By adjusting the length of the column, different notes can be played.

Why does length of a straw affect pitch?
The length of a straw affects pitch because it determines the length of the air column in the straw. Shorter straws have a shorter air column, leading to higher pitch sound vibrations, while longer straws have a longer air column, leading to lower pitch sound vibrations. The pitch is determined by the frequency of the vibrations produced by the air column, with shorter columns producing higher frequencies and higher pitches.
What are the properties and characteristics of an air column?
An air column is a column of air that can vibrate and produce sound. Its properties and characteristics include length, density, temperature, and pressure, which affect the speed of sound waves traveling through it. The length of the column determines the pitch of the sound produced, with longer columns producing lower pitches. Changes in density, temperature, and pressure can also affect the speed and quality of sound waves in the air column.

A 10cm column of air trapped by a column of mercury of 8cm long in capillary tube horizontally at 1 atmospheric pressure The length of air column when the tube is fixed vertically with open end up?
The pressure exerted by a column of mercury is given by the equation P = hρg, where h is the height of the column, ρ is the density of mercury, and g is the acceleration due to gravity. Since the pressure inside and outside the tube remains the same, the length of the air column will be the same when the tube is fixed vertically. Therefore, the length of the air column will be 10 cm.
