Acar has a mass of 1200 kg. a man can comfortably push down with a force of 400 n. if the small piston in a hydraulic jack has an area 6 cm2, what is the minimum area of large piston that would enable the man to lift the car? (g 98 ms2) the the man pushes the small piston down 20 cm. how high does this lift the car?

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

What’s #16 asking me and how do i solve it?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
