Answer:
We will see a waveform displayed on the screen and it will be PWM(pulse width modulation) of sinusoidal wave,this wave should have a frequency of 14KHz and it will form a vibration spectrum.
Answer: hello attached below is the diagram which is part of your question
Total entropy change = entropy change in cold reservoir + entropy change in hot reservoir = -0.166 + 0.083 = -0.0837 kj/k it violates Clausius increase of entropy which is Sgen > 0
Explanation:
Clausius statement states that it is impossible to transfer heat energy from a cooler body to a hotter body in a cycle or region without any other external factors affecting it .
applying the increase in entropy principle to prove this
temp of cold reservoir (t hot)= 600 k
temp of hot reservoir(t cold) = 1220 k
energy (q) = 100 kj
total entropy change = entropy change in cold reservoir + entropy change in hot reservoir = -0.166 + 0.083 = -0.0837 kj/k
entropy change in cold reservoir = Q/t cold = 100 / 600 = -0.166 kj/k
entropy change in hot reservoir = Q / t hot = 100 / 1220 = 0.083 kj/k
hence it violates Clausius inequality of increase of entropy principle which is states that generated entropy has to be > 0
Answer:
Tesla CEO Elon Musk tweeted that the company's stock was too high, and it immediately dropped in value. The tweet may have violated a deal Musk made with the SEC about his tweets and Tesla. Musk also tweeted patriotic lyrics, said his girlfriend Grimes is mad at him, and noted that their child is due on Monday
Answer:
When possible, use public transportation, walk, or ride a bike
Explanation:
Answer:
A) Level D ( before development )
B) Level E ( After development )
Explanation:
A) Calculate the level of service before the development
First we calculate the base free flow speed ( BFFS )
= posted speed limit + 5 mi/hr.
= 50 + 5 = 55mi/hr.
Next determine free flow speed ( FFS )
= BFFS -
= 55 - 6.6 - 0.65 - 0 - 2.25 = 45 mi/hr.
The remaining part of the solution is attached below
The level of service = D
given that:
Vp = 1537.096 pc/hr/In
Density = 34.157 pc/mi/In
FFS = 45 mi/hr
B ) Calculate the level of service after the development
attached below is the detailed solution
The level of service = E
given that
Vp = 1816.568 pc/hr/In
Density = 40.368 pc/mi/In
FFS = 45 mi/hr
