The average atmosphere pressure on earth is approximated as a function of attitude by the relation Patm = 101.325 (1 – 0 02256z)5.256, where Patm is the atmosphere pressure in kPa and z is the altitude in km with z = 0 at sea level. Determine the approximate atmosphere pressures at Atlanta (z = 306 m), Denver (z = 1610 m), Mexico City (z = 2309 m), and the top of Mount Everest (z = 8848 m).

- A small solid ball is released from rest while fully submerged in a liquid and then its kinetic energy is measured when it has moved 4.10 cm in the liquid (if it moves). The figure gives the results after many liquids are used: The kinetic energy K is plotted versus the liquid density plig, and Kg = 1.70 J sets the scale on the vertical axis.

Accounting for this variation using the relation g= a- bz, where a =9.807 m/ s2 and b =3.32 * 10^6 s-2. Determine the weight of an 80-kg person at sea level (z=0), in Denver (z=1610 m), and on the top of Mount Everest (z=8848 m).arrow_forwardThe basic barometer can be used as an altitude measuring device in airplanes. The ground control reports a barometric reading of 753mmHg while the pilot's reading is 690mmHg. Estimate the altitude of the plane from ground level if the average air density is 1.20 kg.m-3 and the barometer fluid is mercury, PHg=13600 kg.m3. To solve this problem determine the atmospheric pressure on the ground and then in the air using the barometric pressure readings. Then using the pressure difference between the ground and the plane, the altitude can be derived by considering a column of air from the ground up to the plane, of constant density, in a similar manner to the barometer.
