When someone is struct by lightning, the electricity passes through the body, into the earth. Here, our body acts as a lightning conductor to complete the earthing process.
-- The boiling points of the first group are all at temperatures
that are way lower than a comfortable room.
. . . . . Nitrogen . . . -320° F
. . . . . Helium . . . . -452° F
. . . . . Neon . . . . . -411° F
The freezing points of the second group are all at temperatures
that are way higher than a comfortable room.
. . . . . Lithium. . . . . . 357° F
. . . . . Sodium . . . . . 208° F
. . . . . Potassium . . . 146 °F
Im sure what is broken down is glucose.
(Anyone feel free to correct me if you think I'm wrong)
Machines are never 100% efficient because they are made by humans and we make errors and nothing we make is perfect, that's why the machines we build are not 100% accurate or efficient.
Answer:
The correct option is D
Explanation:
From the question we are told that
The intensity of the first electromagnetic wave is 
The amplitude of the electric field is 
The intensity of the second electromagnetic wave is 
Generally the an electromagnetic wave intensity is mathematically represented as
Looking at this equation we see that
=> ![\frac{I_1}{I_2} = [ \frac{ E_{max}_1}{ E_{max}_2} ] ^2](https://tex.z-dn.net/?f=%5Cfrac%7BI_1%7D%7BI_2%7D%20%20%3D%20%20%5B%20%5Cfrac%7B%20E_%7Bmax%7D_1%7D%7B%20E_%7Bmax%7D_2%7D%20%5D%20%5E2)
