What force needs to be lifted by a 25 cm diameter hydraulic piston. What force needs to be applied to a 3.5 diameter piston to accomplish this? cm

Explanation / Answer

3.
volume = 2.5*3.8*4
= 38 cm^3
= 38 mL

m = 28 g
density = mass / volume
= 28/38
=0.7368 g/mL
Answer: c

4.
SInce density of water is 1 g/mL, it is less denser than water
hence it will float.
