You already have your separation and dielectric constant so just use the formula you stated towards the end of your question and you get 8.93x10^-11 Farads which is about 89pF</span>
The trachea is a tube that carries air inside the lungs.
Explanation:
Pure substances are typically elements and compound with the following characteristics:
- Pure substances are distinct substances.
- They are homogeneous in all their parts i.e they are the same all through.
- They have a definite composition
- They cannot easily be separated or broken down into simpler substances by physical means.
- Separation by physical means is not easy
- They have a unique sets of physical properties
Impure substances are mixtures. They have the following features:
- Their composition is indefinite i.e they consist of two or more elements and or compounds in any proportion by mass.
- Constituents retain their identities i.e physical properties are retained.
- The constituents reacts differently to changed conditions.
- They can easily be separated into their constituents by physical methods.

Answer:
Explanation:
<u>Joule's Law in Electricity</u>
The Joule's law allows us to calculate the power dissipated in a resistor of resistance R through which goes a current I.
The relation between the voltage and the current is given by Ohm's law:
Solving for I and replacing int the first equation
Solving for V
The second wave because it has the most frequencies. The larger the wave, the more frequencies it has.
