Answer:
Explanation:
Using Pascal laws, which states that pressure are the input equals the pressure at the output.
Pressure is given as force/area
P1=P2
Then,
F1/A1=F2/A2
Cross multiply
F1A2=F2A1
Given that
Ae=0.5m² area of effort
Al=5m² area of load
Fl=? Force if load
Fe= 100N. Force of effort
Then applying pascal
Fl/Al=Fe/Ae
Fl/5=100/0.5
FL/5=200
Fl=200×5
Fl=1000N
The first safety load is 1000N
C. Their strengths are added
Like they said the leopard seal will overpopulate and kill out all of the other animals. Because it would be at the top of the chain then without the killer whale. Therefore, since it is at the top of the chain it will overpopulate because it has nothing to eat/kill it so then they would eat the animals lower than them<span />
