Why do some quasars have red shifts greater than 1?

Physics
1 answer:
Maru [420]4 years ago
6 0

Answer:

D) Einstein proved it is impossible to have a redshift greater than 1; these are all due to gravitational lensing tricking us

Explanation:

By Einstein's theory of relativity the maximum value of the red shift is 1. This correspond to a case in which the observed frequency equals the emitted frequency:

z=\frac{f_e-f_o}{f_o}

in other cases the red shift is lower than one.

Hence, the gravitational lens change the measurements of the observed frequency and because of that we calculate a greater red shift.

Hence, the answer is:

D) Einstein proved it is impossible to have a redshift greater than 1; these are all due to gravitational lensing tricking us

hope this helps!!

A spinning disc rotating at 130 rev/min slows and stops 31 s later. how many revolutions did the disc make during this time?
gayaneshka [121]
F = 130 revs/min = 130/60 revs/s = 13/6 revs/s
t = 31s
wi = 2πf = 2π × 13/6 = 13π/3 rads/s
wf = 0 rads/s = wi + at
a = -wi/t = -13π/3 × 1/31 = -13π/93 rads/s²
wf² - wi² = 2a∅
-169π²/9 rads²/s² = 2 × -13π/93 rads/s² × ∅
∅ = 1209π/18 rads
n = ∅/2π = (1209π/18)/(2π) = 1209/36 ≈ 33.5833 revolutions.

expeople1 [14]

Answer:

The volume will not contract to one fourth of the original.

Explanation:

Applying Charles's Law as:

\frac {V_1}{T_1}=\frac {V_2}{T_2}

Given ,  

V₁ = ?

V₂ = 2 L

T₁ = 5 °C

T₂ = 20 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,

T₁ = (5 + 273.15) K = 278.15 K  

T₂ = (20 + 273.15) K = 293.15 K  

Using Charles law as:

V_1=\frac {V_2}{T_2} \times {T_1}

V_1=\frac {2\ L}{293.15 K} \times {278.15 K}

V_1=1.8977 L

Thus, the volume will not contract to one fourth of the original. (1/4 of 2 L is 0.5 L).
