Answer:
meter
The SI unit of distance and displacement is the meter [m].
Explanation:
have advancedd
4 atoms
Explanation:
On the product side, we expect to find 4 atoms of the product.
An atom is the smallest indivisible particle that takes part in a chemical reaction.
An element is a distinct substance that cannot be split-up into simpler substances. Such substances consist of only one kind of atom.
In this reaction we have:
2 elements: Mg O
on the reactant side:
We have two moles of Mg: 2 atoms of Mg
1 mole of oxygen gas: 2 atoms of O
total atoms: 4 atoms
According to the law of conservation of matter "in a chemical reaction, matter is neither created nor destroyed".
We expect to find 4 atoms of products which is MgO on the product side.
2Mg + O₂ → 2MgO + heat

Answer:


Explanation:
= Mass of first object
= Mass of second object
v = Speed of both objects
= Combined velocity
The ratio of final kinetic energy to initial kinetic energy will be

The ratio is 
As the linear momentum is conserved

Divide by
on both sides

The ratio of mass is
