Answer:
1287.5 N
Explanation:
We are given that
Mass of vehicle ,m=2100 kg
Weight of vehicle ,F=20,600 N
Area,A=
We have to find the minimum force that must be applied to the attached piston of area in order to lift the vehicle.
Apply the pascal's law
Answer:
E) ΔP = F * R
Explanation:
Let's look at Ohm's law:
ΔV = I * R
where I is the electric current, ΔV is the potential difference and R is the resistance.
We can derive the relationship between pressure gradient (ΔP), blood flow (F), and resistance (R) by analogy, getting:
ΔP = F * R
or
F = ΔP/R
This means that the flow is proportional to the pressure difference and inversely proportional to the resistance.
A graphical model of energy flow is an energy pyramid; The steps of the energy flow are
Producers: Green plants store solar energy as chemical energy after it being converted by photosynthesis.
Consumers: The are unable to produce food, they live on food produced by green plants.
Decomposers: some bacteria and molds break down the dead bodies of plants and animals step by step and turn them into simpler substances of dead plants and animals.
