11. The mathematical model for the period of a pendulum found in a physics textbook is Z
T = 2
I
& It can be also written as T=4n?l/g. Input the T value you obtain from the .56 m
long pendulum you made and solve for g. How does this value compare to the accepted
value of 9.81 m/s?

Select the three ways that the parallel-plate capacitor differs from a car battery.

The mantle is made up of which structural zones?

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa.
