Starting with this equation dP/ dy = ρg (1) and this relationship P/ Po = ρ/ ρo (2) where Po and ρo are pressure and density at sea level. Assume g is constant and y = 0 at sea level. (a) Determine the variation in pressure in the earth’s atmosphere as a function of elevation y above the sea level. (b) At what elevation is the air pressure equal to half the pressure at sea level?

The atmospheric pressure varies proportionally from sea level to height, and the air temperature drops by 6K for every T km increase (a) Draw a cylindrical volume that is height inside the atmosphere, and then calculate the pressure change and expression (dP/dy-pg) depending on the height. (b) obtain the temperature change of the atmosphere accordingto the height y(km) in the place where the sea level (y-0) is at ToK temperature. (c) obtain a barometric equation which allows for the change...

If we rearrange the ideal gas law to be in terms of density: ρ=PM/RT and also consider the affects of the buoyancy force: dP/dy=−ρg, we can combine these equations to find the atmospheric pressure as a function of height above the ground. Do so to find the air pressure at an elevation of 8838 meters, close to the peak of Mt. Everest. You can assume that g is constant all the way up and so is the temperature (273 K)...

Question 2 (20 points) Venus has mass my = 4.87 x 1024 kg and radius Ry = 6.05 x 103 km. Surface conditions are temperature To = 740 K, and pressure Po = 9.3 MPa. The lapse rate is approximately constant for most of the troposphere, up to 2 60 km where T1 263 K. Its atmosphere can be approximated as 100% carbon dioxide, CO2. You can assume that gravity is constant at its sea-level value. Using your result from...

Because we are dealing in the Earth’s atmosphere (P = 1 atm, maximum), just about everything we discuss can be adequately described by the ideal gas law. This is important to remember as we proceed in this class. a. In class, we will often use the fact that there are ~ 2.5 x 1019 molecules of air cm-3 at sea level. Because you shouldn’t believe everything you hear, please show, mathematically, that this is the case. Start with the ideal...

2. The acceleration equation We have derived in lectures the Friedmann and fluid equations, that describe the evolution of simple cosmologies. The Friedmann equation is usually given (adopting c 1) as where a(t) is the scale factor of the universe, p is the mass (energy) density, and k is constant. (a) (5 points) The simplest (although spectacularly uninteresting) cosmology has zero mass-energy, i.e. ρ 0. Solve the Friedmann equation under this condition to obtain an expression for at(t).

1. A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. (a) What is the initial acceleration of the rocket, assuming you can neglect air resistance?
