The correct answer would be 16m/so
Explanation:
According to Dalton's atomic theory, all the atoms are individual, all the atoms of the same element are identical in properties and mass, the compound is formed from two or more kinds of the atoms, all the matter is made up of small atoms and the chemical reaction is a rearrangement of the atoms.
The discoveries which contradicts the components of Dalton's atomic theory from the given discoveries are:
Nuclear reactions can change an atom of one element into an atom of another element.
Atoms of a given element can have different numbers of neutrons.
Atoms contain smaller particles: protons, neutrons, and electrons.

Immediately upon reaching its lowest point, a falling pendulum bob has its greatest amount of kinetic energy, which is less than the initial amount of potential energy.
remember the law of energy there cannot be any more since it is using the potential energy to move
-- drop it on the floor; -- hit it with a hammer; -- heat it red hot in a flame; -- wrap many turns of wire around it and pass a high AC current through the wire.

A=f/m
Higher mass is less acceleration
