Calculate the mass of Earth’s atmosphere by considering the pressure at the surface (P ≈ 1.013 bar = 1.013 × 105 Pa). Hint: Every square meter of the surface of the Earth experiences the pressure from the atmosphere above it.

A simplified model of how an airplane flies relies on a difference in air pressure between the top and the bottom of the wing. If a Boeing 737 has a mass of 44,400 kg and a total wing area of 81 m2, what difference in pressure (in N/m2) is necessary for the airplane to maintain altitude?

What would be the height of the atmosphere if the air density (a) were uniform and (b) decreased linearly to zero with height? Assume that at sea level the air pressure is 1.00 atm and the air density is 1.28 kg/m^3.

The density of the atmosphere varies drastically with height, but you can use an average density from sea floor to the space in order to calculate its height. If we approximate this average density to be = 1 Kg/m³, what would be height of the atmosphere? HINT: Since the atmosphere is a fluid (in gas form), you can use the hydrostatic pressure formula (P pgh), just solve for h and use P = 1 atm. BTW, this is how the edge of space is defined, if you make it pass the height of the atmosphere you have reached space :)

The atmospheric pressure at the sea level is 500,000 N /m ^2 please estimate the total mass (in the unit Kg) of the earths atmospheric above the sea level of an area of 1m^2? Write answer as a whole number

The temperature of the atmosphere is not always constant and can increase or decrease with height. In a neutral atmosphere, where there is not a significant amount of vertical mixing, the temperature decreases at a rate of approximately 6.5 K per km. The magnitude of the decrease in temperature as height increases is known as the lapse rate (I). (The symbol is the upper case Greek letter gamma.) Assume that the surface pressure is po = 1.013 × 10° Pa where T=293K and the lapse rate is ( -T = 6.5) K -) . Estimate the pressure 3.0 km km above the surface of Earth.

Atmospheric pressure is about 1.00 x 10^5 Pa on average. What is the downward force of the air on a desktop with surface area 2.48 m^2? Convert the downward force of the air on a desktop with surface area 2.48 m^2 to pounds to help others understand how large it is.

The atmospheric pressure on an object decreases as altitude increases. If a is the height (in km) above sea level, then the pressure P(a) (in mmHg) is approximated by P(a)=760e-0.13a. Determine the atmospheric pressure at 7.176 km. Round to the nearest whole unit.

Make a plot of pressure vs altitude for a hydrostatic, isothermal atmosphere on Earth, assuming a surface pressure of 1 atm.

By definition, pressure is equal to the force exerted per unit area or P =  F A . Suppose that you place a 22 kg block on the a table.(a) If the bottom surface of the block has an area of 0.44 m2. What is the pressure caused by the block as it sits on the table? (Hint: You will need to find the weight of the block in order to know the force exerted. Use 10 m/s2 for gravity.)P = _______ Pa(b) How would your answer to part (a) change if the are of the block is 0.22 m2?P = ______ Pa
