Answer:
D
Commutator is the answer
Explanation:
The commutator systematically converts the current direction between the rotor and the outer circuit. As the shaft revolves, the commutator converts the course of current in a winding. For a separate armature winding, when a cylinder has reached one-half perfect turn, the winding is now attached so that current passes through it in the reverse of the original direction.

Oil and water placed in a jar will separate. Even when shaken and mixed, the oil still separates from the water.
Which best describes oil and water?
Oil and water are highly soluble because they have separate chemical properties.
Oil and water have a low solubility because they have separate chemical properties.
Oil and water are highly soluble because they exert different pressures.
Oil and water have a low solubility because they exert different pressures.

what is dark matter
can we travel faster than speed of light
what is chlorophyll
Answer:
Explaining dark matter and black holes
Here are six big questions about our universe that current physics can’t answer:
What is dark energy, the mysterious energy that appears to be accelerating the expansion of the universe?
What is dark matter, the invisible substance we can only detect by its gravitational effect on stars and galaxies?
What caused inflation, the blindingly fast expansion of the universe immediately after the Big Bang?
For that matter, what caused the Big Bang?
Are there many possible Big Bangs or universes?
Is there a telltale characteristic associated with the death of a universe?
Despite the efforts of some of the world’s brightest brains, the Standard Model of particle physics – our current best theory of how the universe works at a fundamental level – has no solution to these stumpers.
A compelling new theory claims to solve all six in a single sweep. The answer, according to a paper published in European Physical Journal C by Herb Fried from Brown University and Yves Gabellini from INLN-Université de Nice, may be a kind of particle called a tachyon.
Tachyons are hypothetical particles that travel faster than light. According to Einstein’s special theory of relativity – and according to experiment so far – in our ‘real’ world, particles can never travel faster than light. Which is just as well: if they did, our ideas about cause and effect would be thrown out the window, because it would be possible to see an effect manifest before its cause.

Explanation:
Due to travelling faster than light, dark matter has a higher than usual mass in relation to its resting mass, thus accounting for the large 'missing' mass around galaxies. ... Dark matter is therefore non-baryonic, travelling faster than light and has a mass half that of a photon...

A. 207 kJ
B. 4730 kJ
C. 9460 kJ
D. 414 kJ
Answer:
Q = 9460 Kj
Explanation:
Given data:
Mass of copper = 2kg
Latent heat of vaporization = 4730 Kj/Kg
Energy required to vaporize 2kg copper = ?
Solution:
Equation
Q= mLvap
It is given that heat required to vaporize the one kilogram copper is 4730 Kj thus, for 2 kg
by putting values,
Q= 2kg × 4730 Kj/Kg
Q = 9460 Kj
