1. Air resistance force usually upwards, but gravity doenwards.
2. Objects are affected by gravity the same, but air resistance can affect the speed of an object's descent.
Sorry if im wrong
The combined acceleration of all the molecules of oxidized fuel as they emerge from the rocket's nozzles create the thrust that accelerates and propels the rocket
Answer:
The correct answer is - ask a question based on observation and then postulate a hypothesis.

*Make an Observation
*Ask a Question
*Do Background Research
*Form a Hypothesis
*Conduct an Experiment
*Analyze Results and Draw a Conclusion
*Report Your Results
What is that?? Please tell us
Answer:
7.65 m
Explanation:
= Initial pressure = 0.03 atm
= Final pressure = 1 atm
= Inital radius = 21 m
= Intial volume of gas = 
= Final volume of gas = 
= Initial temperature = 200 K
= Final temperature = 323 K
From ideal gas law we have
The radius at liftoff is 7.65 m
