In a car lift used in a se vice station, compressed air exerts aiadius of 5.D0 cm. This pressiure is transmitted by a liq compressed air exert to Iifca can weighing 13.300 NP What air pressure produces this force? Small piston thất has a čircular crosS section and a piston that has a radius of15.0 cm. What force must the

Explanation:

Weight of car = 13300 N  sitting on a piston having cross sectional area of 15 cm

pressure required = force / cross sectional area

= 13300 / π R²

= 13300 / 3.14 x .15²

= 1.88 x 10⁵ N/ m²

force required to lift the car = pressure x area

= 1.88 x 10⁵ x 3.14 x .05² ( 5 cm is radius of small piston )

= 1476 N .

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
