Answer:
The physical topology addresses how devices are connected, while a logical topology addresses how devices actually communicate to one another ( C )
Explanation:
Network physical is simply the process/method of connecting the Network using cables while Logical topology is the general architecture of the communication mechanism in the network for all nodes.
Hence The correct statement is the physical topology addresses how devices are connected, while a logical topology addresses how devices actually communicate to one another

Answer:
isentropic efficiency = 0.818
Explanation:
given data
pressure P1 = 95 kPa
temperature = 27°C
pressure P2 = 600 kPa
temperature = 277°C
to find out
isentropic efficiency of the compressor and exit temperature of the air
solution
we know from ideal gas of properties of air is
Pr1 at 27°C = 1.3860
and h1 at 300 K = 300.19 kJ/kg
and h2 at 550 K = 555.74 kJ/kg
and
we know equation for isentropic process that is
.........................1
put here value we get
![\frac{Pr2}{1.3860} =\frac{600}{95}](https://tex.z-dn.net/?f=%5Cfrac%7BPr2%7D%7B1.3860%7D%20%3D%5Cfrac%7B600%7D%7B95%7D)
solve we get Pr2
Pr2 = 8.75
by ideal gas of properties of air will be at Pr2
h2s = 508.66
T2s = 505.5 K
'so
isentropic efficiency will be here as
isentropic efficiency = ![\frac{h2s-h1}{h2-h1}](https://tex.z-dn.net/?f=%5Cfrac%7Bh2s-h1%7D%7Bh2-h1%7D)
isentropic efficiency = ![\frac{508.66-300.19}{555.74-300.19}](https://tex.z-dn.net/?f=%5Cfrac%7B508.66-300.19%7D%7B555.74-300.19%7D)
isentropic efficiency = 0.818
