Answer: unequal forces
Explanation: in order for something to accelerate it must speed up or slow down . When unequal forces react it casuse a change in motion which is also know as acceleration .
-- If there are only <em>10</em> elements in the universe that can make compound molecules, and a compound molecule can be formed by combining 1, 2, 3, or 4 different elements, then that's already the possibility of at least 400 different molecules.
-- There are many more than 10 elements that can combine to form compound molecules.
-- Every single "<em>organic</em>" molecule, of which there are thousands, is the combination of <em>carbon</em> with other elements.
-- Most all of the substances that can be distilled out of oil, including the paraffin waxes, the alcohols, gasoline, kerosene, butane, propane, octane, and natural gas, are made of just carbon, hydrogen, and oxygen, only with different numbers of each one.
-- Plastics, drugs, rubber, and DNA are examples of molecules that are made of <em>hundreds</em> of atoms.

Explanation:
Answer:
Mass and time are not vector quantities .
Explanation:
All the physical quantities can be classified into two major categories that is :
Scalar quantities
- They are those that describes only the magnitude and they are regarded as incomplete quantities as they don't provide complete information.
For example : Speed ,Mass, Time etc
Vector quantities
- They are complete quantities that can be described in magnitude as well as direction .
For example : Velocity ,gravity ,Acceleration etc
