Use the law of conservation of momentum to determine the answer to the following question:In a closed system, there are two hockey pucks both with a mass of 0.25 kg. One is traveling at 2 m/s. The other is at rest. What is the momentum of this group of objects.

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).

idk what is it? is this a question that you know the answer or u dont

the elements that are used in nuclear fission and their products are much heavier than helium.
