5.1 divided by 104 is 0.05 to the nearest tenth
Answer:
The index of refraction for Medium 2 would be 1.25
Step-by-step explanation:
We have the following data:
Speed of light in Medium 1 = V₁
Speed of light in Medium 2 = V₂
The speed of Light in Medium 2 is related to speed of light in Medium 1 as:
V₂ = 0.8 V₁
Moreover, it is given that Medium 1 is air with index of refraction equal to 1. i.e.
n₁ = 1
We need to find the index of refraction for medium 2. Lets name it is as n₂.
Snell's law related the above mentioned 4 quantities by following relation:
The ratio of indices of refraction of 2 mediums is equivalent to the reciprocal of ratio of phase velocities in those 2 mediums. Mathematically, this can be written as:

Substituting the values we have gives us:

This means, the index of refraction for Medium 2 would be 1.25
The digit in the hundred millions place is 9.
Answer:
If
is people and
is hot dogs, the equation is
.
Represent even numbers as "2n" since each is a multiple of 2.
Represent odd numbers as "2n+1" since each is one more than an even.
-----------------
Your problem:
smaller # : 2n
larger #: 2n+2
-------------------
EQUATION:
2n+2 + 3(2n) = 234
8n = 232
n = 29
---------
smaller = 2*29 = 58
larger = 2n+2 = 60
