Holaa, me quedaron trabajos pendientes de físico química y si alguno me los puede resolver, se los agradecería mucho. Paso a copiar la tarea para que sepan lo que tengo que hacer.

1) En sus carpetas, calculen la masa atómica relativa del neón teniendo en cuenta los siguientes datos.

Elemento (N° A)    |      abundancia %
   Neón (20)         |            90,9 %
    Neón (21)          |             0,30 %
    Neón (22)         |             8,8 %

Recuerden que cada valor de N° A debe ser multiplicado por su abundancia. Luego se suman los resultados de los tres isótopos y se divide por el 100%.

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
