a small piece of mass 40 g is attached to the end of the light string of length 50 cm and allowed to hang freely. the lead is displaced to 0.5cm above its rest position, and then released. Calculate the period of the resulting motion, assuming it is simple harmonic. Calculate the maximum speed of the lead mass.​

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
