Answer:
True
Explanation:
Nikola Tesla defeated Thomas Edison in the AC/DC battle of electric current.
Answer:
a)supplying the intake of an engine with air at a density greater than the density of the surrounding atmosphere
Explanation:
Supercharging is the process of supplying the intake of an engine with air at a density greater than the density of the surrounding atmosphere.
By doing this , it increases the power out put and increases the brake thermal efficiency of the engine.It also increases the volumetric efficiency of the engine.
So the our option a is right.
Answer:
d
Explanation:
is the because that's the amount of work in making machine can do producing heat
Answer:

The entropy change of the carbon dioxide is -0.1104 kJ/kg.K
Explanation:
We are given that carbon dioxide undergoes a process in a closed system.
We are asked to find the entropy change of the carbon dioxide with the assumption that the specific heats are constant.
The entropy change of the carbon dioxide is given by

Where Cp is the specific heat constant
Cp = 0.846 kJ/kg.K
R is the universal gas constant
R = 0.1889 kJ/kg.K
T₁ and T₂ is the initial and final temperature of carbon dioxide.
P₁ and P₂ is the initial and final pressure of carbon dioxide.




Therefore, the entropy change of the carbon dioxide is -0.1104 kJ/kg.K
