Two technicians are discussing hydraulics. Technician A says that if pistons of the same size are used, motion and force can be
1 answer:
the correct option is A. Only technician B is correct.
Hydraulics works on the pascal law, which states that in a direction the hydro static fluid pressure remains constant.
Px=Py=Pz
Since small piston has small area compare to the large piston
Pbig=Psmall
Fbig/Abig=Fsm/Asm
Fbig=
thus the force on the large piston will increase, but it travel small distance.

Answer:
Energy stored, E = 0.072 J
Explanation:
Given that,
Capacitance,
Capacitance,
These two capacitor are connected in parallel, and charged to a potential difference of, V = 60 volts
We know that in parallel combination of capacitor, the equivalent capacitance is given by :
The energy stored in the capacitor is given by :
So, the energy stored in the capacitor in this capacitor combination is 0.072 J.
