Tom wants to climb a mountain. A mountain is 8849m high. Atmospheric pressure decreases exponentially the higher one ascends. he knows that this is the greatest dangers of an expedition above 8000m. The atmospheric pressure at sea level is about 1013 hpa. If pressure is 12% lower at 1000m above sea level, find the atmospheric pressure.
Don't get distracted by the story. The only real question is
what is 12% lower than 1013?
1013(1 - 0.12) = ____
Please give me the solution pls.....
Tom wants to climb a mountain. A mountain is 8849m high. Atmospheric pressure decreases exponentially the higher one ascends. he knows that this is the greatest dangers of an expedition above 8000m. The atmospheric pressure at sea level is about 1013 hpa. If pressure is 12% lower at 1000m above sea level, find the atmospheric pressure.
how to solve this question when there is a formula of this:
P(d)=Po e^kd, where d is distance (m), Po is pressure at sea level(hpa) and P(d) is pressure at some distance above sea level(hpa).
To find the atmospheric pressure at 1000m above sea level, we can use the given information that the pressure is 12% lower at this altitude.
First, let's calculate the pressure difference between sea level and 1000m above sea level.
Pressure difference = 12% of 1013 hPa
= 0.12 * 1013 hPa
= 121.56 hPa
Now, we can find the atmospheric pressure at 1000m above sea level.
Atmospheric pressure (at 1000m) = Pressure at sea level - Pressure difference
= 1013 hPa - 121.56 hPa
= 891.44 hPa
Therefore, the atmospheric pressure at 1000m above sea level is approximately 891.44 hPa.
Keep in mind that this calculation assumes a linear decrease in pressure with altitude, but in reality, atmospheric pressure decreases exponentially as one ascends.
