10 cycles: 50g took 5.15 seconds 100g took 8.1 seconds 250g took 12.75 seconds
1 period for 50g is 0.515 seconds 100g is 0 81 seconds and 250g is 1 275 seconds. You may have noticed that there is a connection between the mass on the spring and time it takes to go through one cycle of motion. Refer to your textbook for the equation that would
enable you to calculate the spring constant

2. Using the equation T=2pie square root of m over k cubed. Where m is the mass of the object on a spring, and k is the
spring constant (which tells you how stiff the spring is) calculate the spring constant from each
of the springs. Then calculate your average spring constant between the two springs Write out
all steps and the final answers below
3. You should have used two different masses in steps 1 and 2 Now estimate the period of one
swing from the third mass, using the spring constant and equation in #2 Write out your work

In a steady-flow steam power plant system, two adiabatic high-pressure and low-pressure turbines ane used to generate power. superheated steam enters the high-pressure turbine at 8 mpa and 550°c. the steam expands in the high-pressure turbine to a saturated vapor at 3 mpa. in order to increase the powe generation of the power plant, another steam turbine working in a lower pressure ranges is deployed. the outlet vapor from the first turbine is heated up at a boiler to the temperature of 500 c at the constant pressure of first turbine's outlet (3 mpa). then, the vapor enters the second turbine and produces extra work. the exit conditions of the second turbine are 5o kpa and 90 percent quality. if the total power output of the power plant is 25 mw, determine a) the mass flow rate of the water (kg/s). b) heat transfer rate in the boiler (mw).
