Which of the following distances is the shortest? 0.007 km 0.2 cm 30 mm 580 mm

Option (b) is the correct answer.

Explanation:

Since, all the given distances are present in different units. So, convert them into same unit.

As there are 1000 meter present in 1 kilometer so, we convert all of them into meter as follows.

                           = 7 m

There are 0.01 m present in 1 cm.

So,     = 0.002 m

There are 0.001 m present in 1 mm.

So,     = 0.03 m

        = 0.58 m

Thus, we can conclude that out of the given options shortest distance is 0.2 cm.

i think that is the right

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).
