The answer is below
Explanation:
Pascal's law states that pressure is exerted in all parts of a static fluid equally.
The area of the narrower arm with a radius of 0.05 m (5 cm) is given as:
Area of narrow arm = π(0.05)²
The area of the wider arm with a radius of 0.18 m (18 cm) is given as:
Area of narrow arm = π(0.18)²
The ratio if the wider arm area to the narrow arm area = π(0.18)² / π(0.05)² = 12.96
To move the 12000 N car, the amount of force needed = 12000/12.96 = 926 N
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.
