For a distant astronomical object (a quasar) is moving away from us at half the speed of light, the speed of the light we receive from this quasar is mathematically given as c = 3x108 m/s
<h3>What is the
speed of light?</h3>
Generally, the equation for the is mathematically given as
The speed of light can be said to be measured to be approximately the value c = 3x108 m/s
.
In conclusion, An will not influence 3x108 m/s unless both are inertia and frames refrences where newtons laws are valid, so the speed of light measured from the earth frame is equal to 3x108 m/s

Explanation:
The linear momentum of a particle is defined as the product of the mass of the particle times the velocity of that particle. Conservation of momentum of a particle is a property exhibited by any particle where the total amount of momentum never changes. Linear momentum of a particle is a vector quantity and is denoted by →p
Answer:
v₁ =0.19 m/s and v₂ = 0.18 m/s
Explanation:
By conservation of energy and conservation of momentum we can find the velocity of each object after the collision:
<u>Momentum:</u>
Before (b) = After (a)
(1)
<u>Energy:</u>
Before (b) = After (a)
(2)
<u>From equation (1) we have:</u>
(3)
<u>Now, by entering equation (3) into (2) we have: </u>
(4)
By solving equation (4) for
, we will have two values for
We will take the average of both values:
Now, by introducing this value into equation (3) we can find
:
![v_{2a} = \frac{7.31 kg*m/s - 26.5 kg*0.19 m/s}{12.5 kg}](https://tex.z-dn.net/?f=v_%7B2a%7D%20%3D%20%5Cfrac%7B7.31%20kg%2Am%2Fs%20-%2026.5%20kg%2A0.19%20m%2Fs%7D%7B12.5%20kg%7D)
Therefore, the velocity of object 1 and object 2 after the collision is 0.19 m/s and 0.18 m/s, respectively.
I hope it helps you!
Explanation:
Formula for path difference is as follows.
x = 2tn
and, refractive index (n) = ![\frac{\lambda}{2t}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Clambda%7D%7B2t%7D)
Thickness is calculated as follows.
Thickness (t) = ![\frac{volume}{area}](https://tex.z-dn.net/?f=%5Cfrac%7Bvolume%7D%7Barea%7D)
Area = ![\pi r^{2}](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D)
= ![\pi \times (\frac{d}{2})^{2}](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20%28%5Cfrac%7Bd%7D%7B2%7D%29%5E%7B2%7D)
= ![\frac{0.49 \times 10^{-6}}{3.14 \times 0.01 m}](https://tex.z-dn.net/?f=%5Cfrac%7B0.49%20%5Ctimes%2010%5E%7B-6%7D%7D%7B3.14%20%5Ctimes%200.01%20m%7D)
=
m
Now, the refractive index will be calculated as follows.
For drop, n = ![\frac{\lambda}{2t}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Clambda%7D%7B2t%7D)
For B drop, n = ![\frac{\lambda}{26t}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Clambda%7D%7B26t%7D)
So, n = ![\frac{640 \times 10^{-9}}{26 \times 1.56 \times 10^{-8}}](https://tex.z-dn.net/?f=%5Cfrac%7B640%20%5Ctimes%2010%5E%7B-9%7D%7D%7B26%20%5Ctimes%201.56%20%5Ctimes%2010%5E%7B-8%7D%7D)
= ![\frac{640 \times 10^{-9}}{40.56 \times 10^{-8}}](https://tex.z-dn.net/?f=%5Cfrac%7B640%20%5Ctimes%2010%5E%7B-9%7D%7D%7B40.56%20%5Ctimes%2010%5E%7B-8%7D%7D)
= 1.5
Thus, we can conclude that index of refraction of the oil is 1.5.
