The diagram shows two sets of vectors that result in a single vector.
What are the first two steps for finding the magnitude of
the resultant vector?
200 m
50 m
find the square of the first horizontal vector and the
square root of the first vertical vector
O find the square root of the first horizontal vector and
the square root of the second horizontal vector
find the sum of the two horizontal vectors and the
sum of the two vertical vectors
find the difference between the two horizontal vectors
and the difference between the two vertical vectors
R
250 m
100 m

4. if you were an astronaut on the moon, what would you experience? what would you see from your perspective?

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.
