Answer:
The laws are: (1) Every object moves in a straight line unless acted upon by a force.
(2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass.
(3) For every action, there is an equal and opposite reaction.
Answer:
Conversion gives 42,107 km in total
Explanation:
A marathon covers 26 miles and 285 yards.
If 1 kilometer is 0.6214 miles, then how many kilometers are 26 miles, then:
1 km = 0.6214 miles
X = 26 miles
X = 41,841 km
Now if 1 yard is 36 inches, how many inches is 285 yards?
1 yard = 36 inches
285 yards = X
X = 10260 inches
If an inch is equal to 2.54 cm, how many centimeters are 10260 inches?
1 inch = 2.54 cm
10260 cm = X
X = 26060.4 cm
And 26060.4 cm is 0.260604 km
Finally, the sum of the distance would be:
41.841 km + 0.260604 km = 42.107 km
I think it's <em>80 . 12</em>

Answer:
An atom cannot be subdivided into smaller particles. (Option A).
Explanation:
According to Dalton's atomic theory: All matter is composed of tiny particles called as atoms. Some postulates of this theory are given below:
1) An atom cannot be subdivided into smaller particles it means they are indivisible.
2) Different element atoms have different masses, and chemical properties.
3) All atoms which are present in an element are identical in all respects such as mass, chemical properties, etc.
4) Atom cannot create or destroyed in a closed system.
5) The types of atoms, and relative number are constant in a given compound.
