Answer:The pressure of Mercury = 588,600Pa
Explanation:
The pressure of Mercury is given as
p=h x ρ x g
Where h =height= 20 dm
changing to meters
10 decimeters (dm) =1 meter
20dm =2 meter, 2m
ρ is the density =30000-kg/m³
g , gravity = 9.81-m/s²
Pressure = 2.0m x 30000-kg/m³ x 9.81-m/s²
588,600 kg.m/ s²/m² =588,600 N/m²
The pressure of Mercury=588,600Pa
C. formal regions are known as "formal" because of the characteristics known by the people who live there and/or visit there
Hello! Fossil fuels are NOT renewable resources. A is out. Burning fossil fuels does produce emissions. B is our. Oil and natural gas does not exist in unlimited quantities, so C is out. However, they are the easiest fuels to make in large amounts, which is why a lot of them are use, despite limited quantities. The answer is D.
