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:
Explanation:
F = qvB
Where F equal to the magnetic force on the particle.
q = charge on the particle
v = velocity of the particle
B =Magnetic field
F = 0.520N
q = 7.4 μC = 7.4×10-⁶C
v = 3×10⁵m/s
B= ?
B = F/qv
B = 0.520/(7.4×10-⁶ ×3×10⁵)
B = 0.234T.
Answer:
The second (abbreviation, s or sec) is the Standard International ( SI ) unit of time. One second is the time that elapses during 9,192,631,770 (9.192631770 x 10 9 ) cycles of the radiation produced by the transition between two levels of the cesium 133 atom. ... One second is equal to 1/86,400 of a mean solar day.
