Describe the normal modes of oscillation
Two harmonic oscillators A and B, of mass (m) and spring constants kA and kB, respectively, are coupled together by a spring of spring constant kC. Find the normal frequencies w' and w" and describe the normal modes of oscillation if kc^2 = kA*kB

Steam at 200 C and 7 bars enters a mixing tank at a rate of 3 kg/min through a pipe with a cross-section of 1.20 cm^2. Liquid water at 30 C and 7 bars enters the tank through another pipe at a rate of 25 kg/min.
Find how many positive integers with exactly four decimal digits, that is, positive integers between 1000 and 9999 inclusive, have the following properties:
Steam at 7 bars and temperature T enters an adiabatic mixing tank. compressed water at 40 C and 7 bars enters at another opening, and the mixture leaves as a saturated vapor at 7 bars.
