A piston of small cross-sectional area a is used in a hydraulic press to exert a small force f on the enclosed liquid. A connecting pipe leads to a larger piston of cross sectional area A. a) What force F will the larger piston sustain

force on larger piston =

Explanation:

we label the pistons as piston A and piston B

small piston A:

area = a

force = f

large piston B:

area = A

force  = ?

Pascal's law of pressure state that the pressure delivered to a liquid is transmitted undiminished to every portion of the fluid.

we know that pressure = force ÷ area

pressure of piston A =

pressure of piston B =

obeying Pascal's law, the system pressures must be equal. Therefore

force on large piston (B) = F =

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

heat is transmitted by radiation
