The overall change in velocity is just 20m/s.
Answer: Option (A) is the correct answer.
Explanation:
When more and more energy is provided to a gas then its atoms move more rapidly.
This rapid and continuous movement converts the gas into hot ionized ions which have positively charged ions and negatively charged electrons.
Therefore, we can conclude that as the atoms move faster, the gas can change into a plasma.
Your answer is most certainly D. Water
That completely depends on your speed and the trajectory (path) you choose.
The Apollo missions took about 3 days each way.
The New Horizons spacecraft passed the moon within a couple of hours after it was launched.
