kakarotiño Posted April 21, 2013 Report Share Posted April 21, 2013 en la primera tienes que multiplicar por el inverso del logaritmo que seria 10^x y luego igualarlo a 7,7 y despejar la energia en al segundo solo es reemplazar los 18 en la (-x)y te da el resultado Link to comment Share on other sites More sharing options...
ingmarov Posted April 21, 2013 Report Share Posted April 21, 2013 7.7=(2/3)log(E/E0)donde E0=104 J7.7(3/2)=log(E/E0)implica que 107.7(3/2)=E/E0por tanto E=E0*107.7(3/2)=104107.7(3/2) = 104+(77/10)(3/2) =104+231/20=10311/20 J Link to comment Share on other sites More sharing options...
