Differential Equation Help -- Vibrating String
Homework Statement
Suppose a tightly stretched vibrating string has a variable density \rho(x). Assume that the vibration is small and is only in the vertical direction (transverse-vibration). Derive teh PDE taking into consideration the gravity...
How much work would it take to push two protons very slowly from a separation of (a typical atomic distance) to (a typical nuclear distance)?
If the protons are both released from rest at the closer distance in part A, how fast are they moving when they reach their original separation...
