Answer:
force acting on small piston is 200 N
Explanation:
given data
cross-sectional area a = 2.0 cm² = 2 × m²
cross-sectional area a = 100 cm²= 100 × =m²
force f = 10,000 N
to find out
force acting on small piston
solution
we know that here pressure will be equal at all level in horizontal
so pressure at p1 = pressure p2
and pressure =
so =
put here value we get
=
solve it we get
force 1 = 200 N
so force acting on small piston is 200 N
c) so they could benefit from using the most accurate measurement system

Hi, the answer to this would be the conservation of mass.
Some history on this: The law of the conservation of mass was founded by a french chemist named Antoine Lavoisier, and stated that: matter cannot be created or destroyed in a chemical reaction.
Hope this helps and if you have any more questions you can message me and I'll be glad to help. :)
The correct answer of this question is : A) Change alternating current into direct current.
EXPLANATION :
As per the question, we are given vacuum tube. Vacuum tube can be of various types. Normally it contains two electrodes called cathode and anode which are enclosed in an evacuated glass chamber . There are also other types of vacuum tubes which contain extra electrodes like control grid .
The vacuum tube can be used as a rectifier. It means that it can be used as an electronic device which will convert alternating current into direct current. It may be a half wave rectifier or a full wave rectifier. Actually the direct current obtained during the rectification of alternating current is pulsating in nature.
Hence, the correct answer is that a vacuum tube can be used to change alternating current into direct current.
