[3] the areas of the car lift pistons, shown in
Figure, are A1 =25 cm2 and A2 =500 cm2. The car
and the right piston have a total weight of 104 N,
while the left piston has a negligible weight and is
at a height h=10m with respect to the right one.
The apparatus is filled with oil of density p =800
kg/m3. What is the value of the force Fı needed to
keep the system in equilibrium?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
