The manufacturer of a 6v dry-cell flashlight battery says that the battery will deliver 15 ma for 60 continuous hours. during that time the voltage will drop from 6v to 4v. assume the drop in voltage is linear with time, how much energy does the battery deliver in this 60h interval?

If y gets smaller as x gets bigger and y have an relationship?

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.
