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
To change the equation, you'd have to take the square root of both sides. When you do this, x^2 cancels out leaving you with x = sqrt(y)
If you need help on the other ones, all you have to do is solve for x by using either addition/subtraction or dividing/multiplying.
