40 points and brainiest
Describe how current climate trends (from 1880 to 2010) might change the pattern of warming and cooling shown on the Vostok ice core graph.
youll have to look at my previous questions to find the graphs so because of this i will be giving out 40 points and brainiest

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.
