The statement “force equals mass times acceleration (F=ma)” is Newton’s second law of motion. Why is this a law rather than a theory? A-It states, rather than explains, the relationship between the variables.

B- .It cannot be proven, whereas a theory can be proven.

C-.It may be revised if new information shows that the relationship has changed.

D- It was classified as a law because it is related to other similar discoveries.

Newton’s second law of motion is a law rather than a theory because: A. It states, rather than explains, the relationship between the variables.

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

×

This ultimately implies that, Newton's Second Law of Motion is a law because rather than explain, it states the relationship between the three (3) variables;

Force.Acceleration.Mass.

In conclusion, a law can be proven whereas a theory may be revised in the event that a new information shows that there is a change in relationship between the variables.

1) the mayans built pyramids just like the egyptians. the mayans also used hieroglyphics like them.2) power was passed down by family. for example, if the father dies, the son would be the next king.3)they both built pyramids for their structures.4)the main crop for the mayans was maize.5)they also grew manioc, beans,  squash,  amaranth, and chile peppers.

Answer:

it provides an alternative energy pathway for the reaction to proceed.

explanation:

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
