Hello there!

The correct answer to your question is c.

This is because one of the main claims to the Big Bang Theory is that "the universe is constantly expanding outwards."

When various objects, say galaxies, recede from us, their light's wavelength is elongated. This, in turn, results as the galaxy's light to look red.

When these objects are moving <em>closer</em> to us, it shortens the wavelength, creating a blue light. In terms of the Big Bang Theory, this should not happen, because everything is moving <u>out</u>.

I hope this helps!

The whale shark the largest of fish and can have the mass of three adult elephants. Suppose that a crane is whale shark into a t
Alona [7]

Answer:

Mass, m = 20000 kg

Explanation:

The force acting on the shark, F=2.5\times 10^4\ N

Acceleration of the shark, a = 1.25 m/s²

We need to find the mass of the Shark. The force acting on an object is given by :

F = ma

m is the shark's mass

So,

m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20000\ kg

So, the mass of the Shark is 20000 kg.

The nearest star to Earth is Proxima Centauri, 4.3 light-years away.
PIT_PIT [208]

Answer:

a) v = 2,152 10⁸ m / s   b)   t = 2.71 10⁸ s  or t =  85.93 year

Explanation:

a) In this special relativity exercise we have that time is measured in the same ship, so it is the proper time,

    v = d / t

Let's reduce the distance to the SI system

    d = 4.3 l and (9.46 1015 m / 1ly) = 40.678 10¹⁵ m

    t = 5.0 y (365 day / 1 y) (24 h / 1 day) (3600s / 1h) = 1.89 10⁸ s

Let's calculate

    v = 40.678 10¹⁵ / 1.89 10⁸

    v = 2,152 10⁸ m / s

b) The time seen from the ground for which the ship moves is given by

     t = t₀ / √ (1- (v/c)²)

Let's calculate

     t = 1.89 10⁸ / √ (1 - (2.152 / 2.998)²)

     t = 1.89 10⁸ / 0.6962

     t = 2.71 10⁸ s

Let's reduce this time to years

    t = 2.71 10⁸ s (1h / 3600s) (1day / 24h) (1 and / 365 d)

    t =  85.93 year
