The barometer of a mountain hiker reads 750 mbars at the beginning of a hiking trip and 650 mbars at the end. neglecting the effect of altitude on local gravitational acceleration, determine the vertical distance climbed. assume an average air density of 1.35 kg/m3.

755.1 m

Explanation:

Initial pressure = 750 mbar

Final pressure = 650 mbar

Converting to Pascal

1 mbar = 100 Pa

Initial pressure = 750 mbar = 75000 Pa

Final pressure = 650 mbar = 65000 Pa

ΔP = Pressure difference = 75000-65000 = 10000 Pa

g = Acceleration due to gravity = 9.81 m/s²

Δh = Height difference

ρ = Density of air = 1.35 kg/m³

ΔP = ρgΔh

∴ Vertical distance climbed is 755.1 m

i lost in getting someone back.

i learned that people are really two-faced and no matter how angelic someone appears they always have a devil side and that you cant trust anyone anymore no matter how dear they are to you.

if your wondering who it waz it waz mah still miss her tho
