A massless spring (k=800N/m), attached with a mass (500g) is completely immersed in 1 kg of water. The spring is stretched by 2 cm and released so that it starts vibrating. What would be the order of magnitude of the change in the temperature of water when the vibrations stop completely? (Assume that the water container and spring receive negligible heat and specific heat of mass =400 J/kg K, specific heat of water =4184 J/kg K)

A damped harmonic oscillator has a frequency of 5 oscillations per second. The amplitude drops to half its value for every 10 oscillations. The time it will take to drop to 1000/1 of the original amplitude is close to coefficient of viscosity of water =1 mPas). the Reynolds number for the flow is of the [...]
