[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?
h

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

Can anybody me with this? ? (picture included.)

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
