    I think we have to find out ƴ ant then use dp/p= ƴ/(ƴ-1) dT/T

    dT/dh= - ƴ/(ƴ-1) Mg/Nk with ƴ/(ƴ-1) as a constant is what I remember of the temperature as a function of time. Still I can't comprehend entirely the problem.

    Well remember the work energy theorem First m1 has potencial energy mgR then it starts moving such as the block m1gR=1/2m1v(square2) + 1/2m2v(square2)

    I already got a and b but for c I thought that by equilibrium C will be the same as a, I'm confused could you give me a hint? Thanks.

    Look ellie you're right about b and c and d is 650 =)

    I think that the fecuency remains the same in D. Because source and observer are at rest. By the same I mean that it could be 650 or the one you at c.

    jennifer for b I was thinking if we know N = ft and we derive this wouldn't it be the same f? I mean dN/dt = d(f*t)/dt that results in f. The other idea I had was calculating the wavelenght (lambda = v/f) using the sound velocity and the given f and then
