The rotor is situated inside the stator and is mounted on the AC motor's shaft. It is the rotating part of the AC motor. And while we know this, the major function of the rotor and the stator is helping the motor shaft rotate.
Answer:
7 available
Explanation:
Since 3 colors are available r = 3
Total combination = 35
nCr = 35 ---1
nCr = n!/(n-r)!r!---2
We put equation 1 and 2 together
n-1)(n-2)(n-3)!/n-3)! = 35x 3!
We cancel out (n-3)!
(n-1)(n-2) = 210
7x6x5 = 210
nC3 = 35
7C3 = 35
So If there are 35 combinations, 7 colors are available.
Thank you!
Answer:
The heat absorbed portion that is transformed into work is therefore helpful and accessible for our use, hence it is termed as available energy. But the energy or heat which is of no use is termed as unavailable energy.
Explanation:
A engine requires heat from the reservoir and transforms portion of it into function. The extra heat is expelled (generally atmosphere) to cold reservoir. The refused heat can't be equal to zero, as per the 2nd law of thermodynamics. The heat absorbed portion that is transformed into work is therefore helpful and accessible for our use, hence it is termed as available energy. But the energy or heat which is of no use is termed as unavailable energy.
