PLEASE HELP Marc is asked to raise a flag at the Remembrance Day ceremonies at his
school. If the effort force to raise the flag is 50N and the load force-the
flag plus the rope-is 50N what is the mechanical advantage of the pulley
on the flagpole?*

Calculate the work done by an external agent during an isothermal compression of 1.00 mol of oxygen from a volume of 22.4 l at 10∘c and 1.0 atm pressure to 16.8l

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
