C. can absorb food directly from the enviornment
Answer:
The force produced by the output piston is 400 N.
Explanation:
Given;
area of the input piston, A₁ = 50 cm²
area of the output piston, A₂ = 200 cm²
load on the input piston, F₁ = 100 N
Let the force produced by the output piston, = F₂
From Pascal's principle, the ratio of the input force to the input area is equal to the ratio of the output force to the output area.
Therefore, the force produced by the output piston is 400 N.
