Two snowcats in Antarctica are towing a housing unit to a new location, as
shown in Fig. 4-38.
The sum of the forces
Fa and Fg exerted
on the unit by the
L
horizontal cables is
parallel to the line L,
and
32°
Fa = 4500 N.
Determine FB and
the magnitude of
FA + FB.

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
