A tank 4 m long, 3 m wide, and 2 m deep is filled to the brim with 192 000 N
of paraffin. What is the pressure at the base of the tank?

16,000 N/m^2

Explanation:

Given;

Force = weight of fluid = 192,000N

Length of tank l = 4 m

Width w = 3 m

depth d = 2 m

Pressure is the measure of the force acting perpendicular to a surface per unit area.

Pressure = force/area

Pressure = F/A

Area A at the base = length × width = l×w

Pressure = F/(l×w) = 192000N/(4×3)m^2

Pressure = 16,000 N/m^2

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
