. Scientists form a theory, or a guess.

2. They run experiments.

3. If the experiments agree with the theory, it becomes a law. Therefore, gravity is true, evolution and climate change are guesses, etc.

Both theories and laws could potentially be falsified by countervailing evidence. Theories and laws are also distinct from hypotheses. Unlike hypotheses, theories and laws may be simply referred to as scientific fact.

When water is decomposed into hydrogen and oxygen, these gases cannot combine again to reform water?
Semenov [28]
This statement is false. When water is decomposed into hydrogen and oxygen; these gases are in a position of combining again to reform water. Water is a molecule consisting of one atom of oxygen bound to two hydrogen atoms. The atoms are joined by covalent bonds; however they have addition hydrogen bonds between the partial negative oxygen and the partial positive hydrogen atom.

What force was applied to an object if 35 j of work was done and the object moved 7 m?
Serjik [45]

5N force was applied to an object if 35 j of work was done and the object moved 7 m

A force is an effect that can alter an object motion according to physics and an object with mass can change its velocity or accelerate as a result force and also force is as push or pull and work done by the force on an object means assuming that direction of the force is parallel to the displacement of the object

Then the formula is

W = f × d

Where f is the magnitude of force and d is the displacement of the object

Then W = 35 J is the work done and

d = 7m is the displacement of the object

So rearrange the equation then

F = 35/7 = 5N

5N force was applied to an object if 35 j of work was done and the object moved 7 m
