Answer:
Check the explanation
Explanation:
Energy alance of 2 closed systems: Heat from CO2 equals the heat that is added to air in

1x0.723x
=3x0.780x
⇒
= 426.4 °K
The initail volumes of the gases can be determined by the ideal gas equation of state,
=
= 0.201
The equilibrium pressure of the gases can also be obtained by the ideal gas equation

= 1x(8.314 28.97)x426.4+3x(8.314 44)x426.4
(0.201+1.275)
= 246.67 KPa = 2.47 bar
Answer:
50421.6 m³
Explanation:
The river has an average rate of water flow of 59.6 m³/s.
Tributary B accounts for 47% of the rate of water flow. Therefore the rate of water flow through tributary B is:
Flow rate of water through tributary B = 47% of 59.6 m³/s = 0.47 * 59.6 m³/s = 28.012 m³/s
The volume of water that has been discharged through tributary B = Flow rate of water through tributary B * time taken
time = 30 minutes = 30 minutes * 60 seconds / minute = 1800 seconds
The volume of water that has been discharged through tributary B in 30 seconds = 28.012 m³/s * 1800 seconds = 50421.6 m³
I am not sure I am stuck on this and I have been for 45 min someone please help me and this girl or boy!!
Answer:
The frequency that the sampling system will generate in its output is 70 Hz
Explanation:
Given;
F = 190 Hz
Fs = 120 Hz
Output Frequency = F - nFs
When n = 1
Output Frequency = 190 - 120 = 70 Hz
Therefore, if a system samples a sinusoid of frequency 190 Hz at a rate of 120 Hz and writes the sampled signal to its output without further modification, the frequency that the sampling system will generate in its output is 70 Hz
