    Seesaw physics and center of mass

    I want to write a program that basically mimics the physics of seesaws. Part of a project I'm working on. I understand how equilibrium works and everything, but let's say that I have a mass on each end of the seesaw, and both masses are equal distance from the pivot. If both masses have the...

    What is the minimal velocity boost to bring a satellite down to Earth?

    No, I don't know what R is. Just that it's the orbital radius of the satellite. I don't think I'll get an actual number here. Probably an equation that will allow me to plug in any value for R.

    What is the minimal velocity boost to bring a satellite down to Earth?

    A satellite is orbiting Earth in a circular orbit of radius R. At some point the satellite has to be returned to Earth and so it is given a sudden negative velocity boost in the direction opposite the satellite's forward velocity). The radius of the Earth is r, and the gravitational acceleration...

    Thermodynamics: T-S slope at constant volume

    1. Prove that the slope of an isochoric process in a T-S diagram is T/Cv where T is the temperature and Cv is the heat capacity at constant volume 2. dQ = T * dS (I understand this) dQ = Cv * dT for isochoric processes (I don't understand this) 3. Since the two equations share dQ...

    How Do You Solve This Complex Carnot Engine Problem?

    1. There are two parts to this problem. I'm having trouble with the second part, but I'll include the first part as well since it's probably needed for the second part. Part 1: "A building is cooled by a Carnot engine operated in reverse (a Carnot refrigerator). The outside temperature is...

    Thermodynamics: Heating gas in two separate containers

    1. A cylinder with thermally insulated walls contains a movable frictionless thermally insulated piston. On each side of the piston are n moles of an ideal gas. The initial pressure (P_0), volume (V_0), and temperature (T_0) are the same on both sides of the piston. The value for (gamma) is 1.5...
