Answer:the answer should be dark energy
Explanation:
Answer:
Part a)

Part b)

Explanation:
Part a)
Initial value of magnetic flux is given as


so we have

Final flux through the loop is given as

now EMF is given as



Part b)
If magnetic field is constant while Area is changing
So EMF is given as



Based on the nature of constructive interference,
none of the wave intersections will produce constructive interference.
<h3>What is constructive interference?</h3>
Constructive interference is interference that occurs when two waves of the same frequency amplitude and wavelength travelling in the same direction are superposed with the resultant effect of reinforcement of both waves to produce a larger wave.
Constructive interference occurs when the path difference between two identical waves at a point is:
where n = 0, 1, 2, ...
For the various intersections:
- 1.77 cm crest intersecting with a 0.65 cm crest; n = 1.77/0.65 = 2.7
- A 1.2 mm crest intersecting with a 3.9 mm trough is destructive.
- A 4.55 N trough intersecting with a 1.59 N trough; n = 4.55/1.59 = 2.8
- A 0.44 inch trough intersecting with a 0.72 inch crest is destructive.
- A 7.42 mm trough intersecting with a 1.93 mm trough; n = 7.42/1.93 = 3.8
Therefore, none of the wave intersections will produce constructive interference

Answer:

Explanation:
As the Universe expands, the photons of the cosmic microwave background increase its wavelength, making its temperature inversely proportional to the scale factor of the Universe. That is, as the average distances between galaxies increase, the temperature of the cosmic microwave background decreases by the same factor. Therefore, the temperature when the distances between galaxies are 1.7 times as large as they are today will be:
