Two sound waves, from two different sources with the same frequency, 540 Hz, travel in the same direction at 330 m s . The sources are in phase. What is the phase difference of the waves at a point that is 4.40 m from one source and 4.00 m from the other?

The value is

Explanation:

From the question we are told that

    The frequency of each sound is  

      The speed of the sounds is  

       The  distance of the first source from the point considered is  

        The distance of the second source from the point considered is  

Generally the phase angle made by the first sound wave at the considered point is mathematically represented as

Generally the phase angle made by the first sound wave at the considered point is mathematically represented as

Here b is the distance o f the first wave from the considered point  

Gnerally the phase diffencence is mathematically represented as  

=>      

Gnerally the wavelength is mathematically represented as

=>    

=>    

=>    

=>    

i believe the answer is a

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
