Jowl is a derived unit give reason

Explanation:

Joule is the unit of energy and work done.

It is a derived quantity because it is not a fundamental or basic unit.

A derived unit is formed by the combination of two or more fundamental quantities.

Since work done  = Force x distance

                           Force  = mass x acceleration

                          = mass x acceleration x distance

The unit then becomes kgm²/s²

So, 1joule  = 1kgm²/s²

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
