If radiative forcing were to increase in a particular region of earth, what would you expect to happen to average temperatures? a. average temperatures would decrease. b. average temperatures wouldn't change. c. average temperatures would increase. d. average temperature isn't related to radiative forcing.

Apositive point charge q is fixed on a very large horizontal frictionless tabletop. a second positive point charge q is released from rest near the stationary charge and is free to move. which statement best describes the motion of q after it is released? assume q stays on the table

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

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.
