The lightning efficiency based on the scenario depicted will be C. 56 lumens/Watt, more efficient.
<h3>How to calculate the lightning efficiency</h3>
The efficiency of the incandescent bulb will be:
= 450/40 = 11.25 lumens per watt.
The efficiency of the LED bulb will be:
= 450/8 = 56 lumens per watt.
In this case, the LED bulb is more efficient than the incandescent bulb.
Therefore, the lighting efficiency will be 56 lumens/Watt, more efficient

Answer:
Of course music plays crucial role
Answer:
Explanation:
For this case we have given the following data:
represent the temperature for the air
represent the velocity of the air
represent the specific heat ratio at the room
represent the gas constant for the air
And we want to find the velocity of the air under these conditions.
We can calculate the spped of the sound with the Newton-Laplace Equation given by this equation:
Where K = is the Bulk Modulus of air, k is the adiabatic index of air= 1.4, R = the gas constant for the air, 
the density of the air and T the temperature in K
So on this case we can replace and we got:
The Mach number by definition is "a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound" and is defined as:
Where v is the flow velocity and 
the volocity of the sound in the medium and if we replace we got:
And since the Ma<0.8 we can classify the regime as subsonic.
Answer:
In the passage, it has been mentioned that the president of CFR received the letter from GET, who offered them to install the network servers at the cost of $5 million and the president of CFR also accept it. Although the GET will charge 50 percent more charges after getting the news of heavy tax on technology providers, I will not accept it. As a president of CFR my argument will be that I will ask them (GET) to install the servers at the earlier price that the GET offers before heavy taxation, otherwise, I will reject the offer as I had not formally agreed. Because, the president already informed them about the acceptance of the offer.
My other argument will be that if the GET will not accept my previous proposal, I will go to another technology provider, who can offer the service at a lower cost in comparison to the GET.
