Find the partial derivatives (∂p/∂t)v and (∂p/∂v)t, and apply them to the equation derived from the cyclic rule, (∂v∂t)p=−(∂p∂t)v(∂p∂v)t to find (∂v/∂t)p. express your answer in terms of the parameters, constants, and variables in the van der waals equation (p, vm, r, t, a, and b).

Rethink and reinvent

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?  

Sorry i dont understand the question can you rephase it?

C) the increase in atmospheric pressure pushes the walls of the balloon outward thus making it  is the answer.hope i you.
