Because CMB radiation was _____ throughout the universe, scientists can only relate the source to the big bang.

Physics
1 answer:
erma4kov [3.2K]3 years ago
6 0

Answer: 1 The correct answer is that CMB radiation was spread uniformly throughout the whole universe.This was related to big band theory because this theory predicts that the universe was a very hot place and as it cooled down it should have been filled with laterally the remnant heat over from the Big Bang called as cosmic microwave background.

Answer: 2 CMB radiation was discovered accidentally when Penzias and Wilson were performing some experiment and they noticed a ' hum' noise that was constantly detected by the antenna even after removing all the disturbing sources.

Then it was realized that it is cosmic microwave background radiation.

Artemon [7]

Answer:

calculating displacement.

Explanation:

It's not true that displacement and distance would be the same always. Displacement is always smaller than or equal to distance as it is the smallest path between the initial and final point whereas distance is the measure of the total path covered.

What is the correct order of increasing energy?
Gnom [1K]

Answer:

Microwaves, visible light, ultraviolet light, x-rays, γ-rays

Explanation:

The energy of any wave is given by :

E=h\nu

h = Planck's constant

\nu is the frequency of wave

It is clear that the energy of any wave is directly proportional to its frequency. Gamma rays have maximum frequency. Out of given options microwaves have least frequency.

So, the increasing order of energy is "microwaves, visible light, ultraviolet light, x-rays, γ-rays". Hence, the correct option is (5).

sammy [17]

Answer:

1)  Q ’= 8 Q ,  2)    q ’= 16 q ,  3)   r ’= ¾ r

Explanation:

For this exercise we will use Coulomb's law

      F = k q Q / r²

It asks us to calculate the change of any of the parameters so that the force is always F

Original values

                q, Q, r

Scenario 1

      q ’= 2q

       r ’= 4r

     F = k q ’Q’ / r’²

we substitute

     F = k 2q Q ’/ (4r)²

     F = k 2q Q '/ 16r²

we substitute the value of F

      k q Q / r² = k q Q '/ 8r²

       Q ’= 8 Q

Scenario 2

       Q ’= Q

       r ’= 4r

we substitute

      F = k q ’Q / 16r²

      k q Q / r² = k q’ Q / 16 r²

      q ’= 16 q

Scenario 3

      q ’= 3/2 q

      Q ’= ⅜ Q

we substitute

        k q Q r² = k (3/2 q) (⅜ Q) / r’²

        r’² = 9/16 r²

        r ’= ¾ r
