Seen through a traditional optical telescope, the space between stars and galaxies is pitch black. But, with a radio telescope,

we detect a faint background glow, almost exactly the same in all directions, that is not associated with any star, galaxy, or other object.
This phenomenon, which provides evidence for the Big Bang theory, is called the


A) redshift.

B) singularity.

C) universal field theory.

D) cosmic microwave background.

That's the Cosmic Microwave Background (CMB). (D)

It doesn't "provide evidence for the ... Theory". The Big Bang theory is the best explanation (so far) for the CMB and a lot of other observations.

Evidence isn't used to prove theories. Theories are attempts to explain evidence.

The spherical annulus of cometary nuclei surrounding the solar system is called the ___.
Bingel [31]

Answer:

Oort Cloud

Explanation:

  • Hundreds of millions of comet nuclei forming a spherical region that surrounds the solar system is called Oort cloud.
  • The Oort cloud revolves at tens of thousands of the distance of the earth from the sun.
  • Comets are the condensed water and dust particles that orbit around the sun with inward helix leaving behind a tail of vapours and vaporize completely as they get closer to the sun during their revolution around it.
  • They have a nebulous appearance and extremely elongated orbits.

A piece of wood has a volume of 4.6 cm to the power of 3, and a mass of 3.7 g what is the density of the wood
AysviL [449]

Density is given by:

D = M/V

D = density, M = mass, V = volume

Given values:

M = 3.7g, V = 4.6cm³

Plug in and solve for D:

D = 3.7/4.6

D = 0.80g/cm³

Concept Simulation 20.4 provides background for this problem and gives you the opportunity to verify your answer graphically. Ho

Answer:

The time constant is 1.049.

Explanation:

Given that,

Charge q{t}= 0.65 q_{0}

We need to calculate the time constant

Using expression for charging in a RC circuit

q(t)=q_{0}[1-e^{-(\dfrac{t}{RC})}]

Where, \dfrac{t}{RC} = time constant

Put the value into the formula

0.65q_{0}=q_{0}[1-e^{-(\dfrac{t}{RC})}]

1-e^{-(\dfrac{t}{RC})}=0.65

e^{-(\dfrac{t}{RC})}=0.35

-\dfrac{t}{RC}=ln (0.35)

-\dfrac{t}{RC}=-1.049

\dfrac{t}{RC}=1.049

Hence, The time constant is 1.049.

Que es la expansión del universo?
anastassius [24]

Answer:

La expansión no es más que el incremento con el tiempo de la distancia entre cualquier par de galaxias lejanas. Se suele utilizar para representar este hecho la analogía de un globo donde hemos pintado una serie de puntos a modo de galaxias.
