the first and second law rate equations for an irreversible
process.
Write the first and second law rate equations for an irreversible process where two gases flow into a system exchanging heat and two gases flow out of the system and the gases are kept separate from each other. The system has heat out, Qout at Tout, and no work. The potential energy change can be ignored but not the change in kinetic energy.

let \(\theta\) = 0, what does your
solution predict for the normal force? Does this make physical
sense?

Use Conservation of Mass-Energy to determine how much kinetic energy is released when Radium-224 decays into Radon-220 and Helium-4 (an alpha particle). The relevant masses are mRa = 224.020186u, mRn = 220.011368u, and mHe = 4.002603u. Kinetic energy released: A Uranium-236 nucleus that is initially at rest has a mass of 2.9e-25 kg and is initially at rest. When it decays, it creates two fragments that fly off in opposite directions. Fragment #1 moves to the left at a velocity...

Q.2 Imagine a bungee jumper stepping out of a platform initially with kinetic zero energy. Let us take the system to be the bungee jumper, the bungee cord and the Earth and let us assume that the thermal energy of the system do not change during the jump. MODEL: We can treat the bungee jumper as a particle. The bungee cord is a perfect spring of zero mass, spring constant k and position at rest ye. The system is taken...
