Mercury in a box have density is 30000kg/m^3 height is 20 dm. Determine the pressure of Mercury .​

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

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
