Answer:
It made information easily accessible and ensured individuals became more vast in subject topics of interest.
Explanation:
Information revolution is different and unique and it came with the advent of computers and the internet. A lot of information is stored there which is too large and complex for the human brain.This helped people to access information without much stress as informations about almost every subject is on the Internet.
Individuals can check the informations up and become more vast in interested topics.
Answer:
Q = 8.845 DEGREE
Explanation:
given data:
combine Mass for 6 cylinder (M) =15 Kg/hr
mass of each cylinder (m) = 15/6 = 2.5 Kg/hr = 0.000694 Kg/ sec
Engine speed (N)= 1500rpm
Diameter of one nozzle hole ( d) = 200 micrometer = 0.0002 m
Discharge Coefficient (Cd) = 0.75
Pressure difference = 100 MPa
Density of fuel = 800 kg/m^3
velocity of fuel is
injected fuel volume (V) =Area of given Orifices × Fuel velocity × time of single injection × no of injection/sec
we know that p = m/ V
So
putting these value in volume equation and solve for Discharge
Q = 8.845 DEGREE
Answer:
Yes reversible heat engine is more efficient than irreversible heat engine
Explanation:
A reversible heat engine has more efficiency compared to an irreversible heat engine that is operating between the two same thermal reservoirs. Since the reversible process can do maximum work. Also reversible processes means any one of the process can be reversed without producing any effect on the systems as well as the surroundings, that is there is no loss of energy in case of a reversible process. While in case of irreversible process, there is loss of energy in the form of friction. Thus there is loss of energy in irreversible process, so its efficiency will be less than a reversible process.
Answer:
Moral ethical obligation
Explanation:
He is morally obliged to report the findings to the authorities in order to protect the community from any impending hazard caused by the discharge into the water body.
Under ethics after any future investigation is carried out and he was found out to have carried out analysis, he might be penalized for conspiracy to conspire even if he states categorically that his contract was terminated by xyz for proofing otherwise. This might lead to serious consequences for him.
Answer:
(a) 1.003 MHz
(b) increase the signal-to-noise ratio
Explanation:
The relationship between channel capacity, bandwidth, and signal-to-noise ratio was described by Claude Shannon in the 1940s, based on previous work by Harry Nyquist and Ralph Hartley. The relationship is given by the formula ...
C = Blog₂(1 +S/N)
where C is the channel capacity (bits per second), B is the bandwidth (Hz), and S/N is the signal to noise power ratio.
__
<h3>(a)</h3>
You want to find B for C=10^7 and 10·log(S/N) = 30. Solving for B, we find ...
B = C/log₂(1 +S/N)
B = 10^7/log₂(1 +10^(30/10)) = 10^7/log₂(1001) ≈ 1.003 MHz
The allocated bandwidth must be at least 1.003 MHz.
__
<h3>(b)</h3>
Shannon's relation tells us the alternative to increasing bandwidth is increasing signal-to-noise ratio. If "sufficient" bandwidth is not available, the signal-to-noise ratio must be increased.
