Answer:
The value is
Explanation:
From the question we are told that
The volume of liquid nitrogen is
The density of nitrogen at gaseous form is = The dry air at sea level
Generally the density of nitrogen at liquid form is
And this is mathematically represented as
=>
Now the density of gaseous nitrogen is
=>
Given that the mass is constant
=>
To solve this problem it is necessary to apply the concepts related to frequency as a function of speed and wavelength as well as the kinematic equations of simple harmonic motion
From the definition we know that the frequency can be expressed as
Where,
Therefore the frequency would be given as
The frequency is directly proportional to the angular velocity therefore
Now the maximum speed from the simple harmonic movement is given by
Where
A = Amplitude
Then replacing,
Therefore the maximum speed of a point on the string is 3.59m/s
