Answer:
Earth's first atmosphere 4.6 billion years ago was most likely comprised of hydrogen and helium (two most abundant gases found in the universe!)
Through the process of outgassing, the outpouring of gases from the earth's interior, many other gases were injected into the atmosphere. These include:
-water vapor (produced rain - rivers, lakes, oceans)
-carbon dioxide
-nitrogen
As outgassing occurred over a period of millions of years, the atmosphere evolved to its current state

Answer:
387 volts
Explanation:
Ohm's law is used to relate voltage, current and resistance.
The formula is as follows:V = I * R
where:
V is the applied voltage (measured in volts)
I is the current flowing (measured in amperes)
R is the resistance (measured in ohm)
In the given, we have:
current (I) = 9 amperes
resistance (R) = 43 ohm
Substitute with the givens in the above formula to get the voltage as follows:
V = 9 * 43
V = 387 volts
Hope this helps :)
