The work done on the gas during this process if the final pressure is 456 kPa is; -82.8 kJ
<h3>Workdone in Thermodynamics</h3>
We are given;
The initial pressure; P₁ = 96 kPa
Final Pressure; P₂ = 456 kPa
The gas is compressed according to;
p = aV + b
where;
a = -1200 kPa/m³
b = 600 kPa
Thus, at initial pressure P₁ = 96 kPa;
96 = -1200V₁ + 600
1200V₁ = 600 - 95
1200V₁ = 505
V₁ = 505/1200
V₁ = 0.42 m³
At Final Pressure P₂ = 456 kPa;
456 = -1200V₂ + 600
1200V₂ = 600 - 456
1200V₂ = 144
V₂ = 144/1200
V₂ = 0.12 m³
Formula for the workdone during the process is;
W_out = ¹/₂(P₁ + P₂)(V₂ - V₁)
W_out = ¹/₂(96 + 456)(0.12 - 0.42)
W_out = -82.8 kJ

Answer:
Final Pressure in the tank after letting 0.5 kg out of the tank is 504.6 kPa
Answer:
0.19s
Explanation:
Queueing delay is the time a job waits in a queue before it can be executed. it is the difference in time betwen when the packet data reaches it destination and the time when it was executed.
Queueing delay =(N-1) L /2R
where N = no of packet =93
L = size of packet = 4MB
R = bandwidth = 1.4Gbps = 1×10⁹ bps
4 MB = 4194304 Bytes
(93 - 1)4194304 / 2× 10⁹
queueing delay =192937984 ×10⁻⁹
=0.19s
Answer:
D. Rectangular
Explanation:
This is because rectangular coordinate systems are used in plotting common straight lines graphs with the formulae,
Y = Mx + c
Where y is the vertical coordinate
X is the horizontal coordinate
M is the dlope of the line
C is the y-axis intercept
Generator Hz comes in because competing frequencies in a machine might cause instability and equipment damage. Thus, option B is correct.

What is the role of hertz in the alternator?</h3>
This alternator will produce 30 cycles of voltage in a second if it has two poles. The frequency would thus be defined as 30 cycles per second, or 30 Hertz. The alternator's rotating speed and frequency are directly inversely related.
When compared to a two-pole alternator, a four-pole alternator produces two cycles of voltage in a second (or one hertz of frequency). The number of poles in an alternator has a direct relationship to its frequency.
RPM is a common unit of measurement for engine power (rpm). The ability of an engine to deliver power is indicated by frequency, which is a significant number.
Therefore, Tech B says that hertz is the amount of current flow produced by an alternator.
