Quizplus · Accepted Answer

According to the question, the atmospheric pressure at altitude h is half the pressure at sea level. Therefore, if we let P be the atmospheric pressure at sea level, then the atmospheric pressure at altitude h is P/2. 
Now, we need to find the atmospheric pressure at an altitude 2h. Since the atmospheric pressure halves at every height h, the atmospheric pressure at an altitude 2h would be half the atmospheric pressure at an altitude h. 
So, the atmospheric pressure at altitude 2h would be (P/2)/2 = P/4 = 0.25P. Therefore, the answer is option C, 0.25.

At the Altitude H the Atmospheric Pressure Is Half the Pressure
