A car weighing 16,170 newtons is placed on a hydraulic lift. Piston B has an area of 5,005 cm?
and piston A has an area of 65 cm². What force must be exerted on piston A to lift the car?
P = F/A where Pequals pressure, Fequals force, and A equals area

Mike walks 100 meter north, then walks 30 meters south. after this, he walks another 10 meters north. what is the magnitude of his total displacement during this walk, in meters?

Which accounts for an increase in the temperature of a gas that is kept a constant volume

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
