Explanation:
According to Newtons Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.

The options that belong to Dalton's Law are:
Atoms cannot be created or destroyed.Atoms cannot be broken down into smaller pieces. All atoms of an element are identical.Chemical reactions cause atoms to be rearranged.Explanation:
Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
Dalton based his theory on the law of conservation of mass (this law says that "The mass is not created or destroyed, only transformed", in other words, in a chemical reaction the sum of the mass of the reagents is equal to the sum of the mass of the products) and the law of constant composition (this law says that when two or more elements are combined to give a certain compound, they always do so in a constant mass relationship.)
Dalton's theory states that:
The elements are formed by discrete, tiny and indivisible particles, called atoms, that are not altered in chemical changes. All atoms of the same chemical element are equal in mass and properties and different from the atoms of any other element. The compounds are formed by the union of atoms of two or more elements. The relationship between the number of atoms present in a compound is always an integer or a simple fraction. In chemical reactions there is separation, combination or regrouping of atoms, never creation or destruction of them.Taking into account what was previously stated, the options that belong to Dalton's Law are:
Atoms cannot be created or destroyed.Atoms cannot be broken down into smaller pieces. All atoms of an element are identical.Chemical reactions cause atoms to be rearranged.
