, b)
, c) 
Explanation:
a) Let assume that electric motor is single-phase and operates in DC-mode, so that mechanical power output is:

The current delivered to the motor is:



b) The power delivered to the motor is:



The energy delivered to the motor during 3.80 hours of operation is:

Chromosomes that's the answer
Answer:
Control of air–fuel ratio
Oxygen sensors tell the ECU whether the engine is running rich (too much fuel or too little oxygen) or running lean (too much oxygen or too little fuel) as compared to ideal conditions (known as stoichiometric).
Explanation:
Explanation:
1ml = 2.7g
Xml = 1.5g
Divide 1.5 by 2.7 to find X.
Obviously, since 1.5 is less than 2.7, you know the answer will be less than 1.
