Answer:
When one object uses force to move the other.
Explanation:
This is called Thrust.Thrust is used in airplane engines,or an engine can be a source of Thrust,we use our legs to Thrust us forward when we walk!
Explanation:
The periodic table is an arrangement of the chemical elements, organized on the basis of their atomic numbers, electron configurations and recurring chemical properties.
The true ratio of atoms in a molecule or formula unit is called molecular formula
<h3>What is empirical formula?</h3>
This is the simplest formula that shows the ratio of the different atoms present in a compound.
<h3>What is molecular formula?</h3>
This is the formula of a compound which gives the true or actual ratios of the different atoms present in a compound
<h3>What is molar mass?</h3>
The molar mass of a compound is defined as the sum total of the molar masses of the different atoms present in the compound.
<h3>What is percentage composition?</h3>
This gives the proportion of the different atoms present in a compound.
From the above definitions, we can conclude that the correct answer to the question is molecular formula
