Due to a point isotropic sonic source, loudness at a point is L=60dB If density of air is rho=((15)/(11))(kg)/(m^3) and velocity of sound in air is v=33(m)/(s) , the pressure oscillation amplitude at the point of observation is [I_0=10^-12(W)/(m^2) ]

If E^(@)(M^(+)/M)= -0.44V and E^(@)(X/X^(-)) = 0.33V . From this data one can conclude that:

For the electrochemical cell, M|M^(+) ||X^(-)|X , E_(M^(+)//M)^(@) = 0.44 V and E_(X//X^(-))^(@) = 0.33 V . From this data we can deduce that :

For the electrochemical cell (M|M^(+))|| (X^(-)|X) E^(@) (M^(+)//M) = 0.44V and E^(@) (X//X^(-))=0.33V From this data one can deduce that :

For the electrochemicl cell, M|M^(+)||X^(-)|X E_((M^(+)//M))^(@) = 0.44 V and E_((X//X^(-)))^(@) = 0.33 V From this data one can deduce that :
