    Calculating Work in Isothermal Gas Expansion with Variable R_v

    Yes it is :( I understand that W is equivilent to that equation you wrote, I just don't know how to get an answer with only p_0, V_0 and R_v and not n, T and R

    Calculating Work in Isothermal Gas Expansion with Variable R_v

    Calculate the work W done by the gas during the isothermal expansion (path C). It may be be convenient to generalize your results by using the variable R_v, which is the ratio of final to initial volumes (equal to 4 for the expansions shown in the figure.) Express W in terms of p_0, V_0, and...

    Calculating Boat Speed with Rainfall Accumulation

    I got stuck on the 3rd part of this question: Assume that the boat is subject to a drag force F due to water resistanceThe drag is proportional to the square of the speed of the boat, in the form F=0.5v^2. What is the acceleration of the boat just after the rain starts? I don't even know...

    Differential Calculus Problem Help w/ Complex Numbers

    Just wondering if anyone could help me out with some problems I'm having with differential calculus. Firstly, can anyone confirm if I sketched the region in image 1.jpg correctly (shown in 2.jpg)? I've done questions before where it just says |z|<2 and I know that it looks like a circle, but...

    Blocks being pulled by a string

    I think it does... that would make the Force 3/2*T right? So in terms of m and F, the acceleration would be F/3m ?

    Blocks being pulled by a string

    I'm just starting to get my head around the concepts of Tension and Force but I'm stuck on this question, I was wondering if anyone could help me out? Q: 3 identical blocks connected by ideal strings are being pulled along a horizontal frictionless surface by a horizontal force F. The...
