Answer:
Amplitude
Explanation:
Amplitude is the vertical distance between the baseline to the crest or the horizontal diatance between crest and trough of a wave. Trough is the lowest point of the wave hence called the baseline while crest is the highest point of a wave. The horizontal distance between two successive waves is however called the wavelength and the product of wavelength and frequency gives the velocity of the waves. Note that amplitude has no effect on the velocity of the waves.
Using Planck's equation,
E = nhc / λ
Also, Power = Energy / time
E = 20 x 10⁻³ x 60 x 60
E = 108 J
108 = (2.29 x 10²⁰ x 6.63 x 10⁻³⁴ x 3 x 10⁸) / λ
λ = 4.22 x 10⁻⁷ m
Gas or fog in the air due to evaporation.

<h2>Answer: The second Statement
</h2>
<h2>
The algebraic sum of the currents flowing through each of the three resistors is equal to the current through the battery. </h2><h2 />
In a series circuit, the value of the equivalent resistance 
is equal to the sum of the values of each of them:
Where:
<h2>The equivalent resistance of the combination of resistors is greater than the resistance of any one of three resistors. </h2>
In this case the current 
flowing through the resistors is the same in each one. This is because the current flowing through the circuit only has one way to go, so the current intensity is the same throughout the circuit.
Therefore:
<h2>The current flowing through each of the resistors is the same and is equal to the current through the battery. </h2><h2>The algebraic sum of the voltages across the three resistors is equal to the voltage across the battery. </h2>
The battery provides a voltage 
that is the sum of the different voltages at the ends of the resistors:
Where the Voltage, according to Ohm's law is:
Hence, the second statement of this question is <u>True

Hello There
Answers:
1) BEVs and hydrogen fuel cell vehicles are more promising for the future because they reduce gas emissions as well as CO2 which makes our planet less-pulluted
2) This is an opinion. Mine is that they should be required to at least have it be an option to buy.
I hope this helps
