Which could describe the motion of an object?

distance = 1 meter and displacement = 10 meters

distance = 10 meters and displacement = 100 meters

distance = 0 and displacement = 10 meters

distance = 10 meters and displacement = 10 meters

A)distance = 0 and displacement = 0

B)distance = 10 meters and displacement = 0

D)distance = 10 meters and displacement = 10 meters

F)distance = 10 meters and displacement = 1 meter

In fact, displacement cannot be larger than distance, because distance is the total distance travelled in any direction, while displacement takes into account the direction. When the object moves only in one direction, distance and displacement are equal; however, if the motion of the object consists of several motions into more directions (like going back and forth), the distance travelled is always larger than the displacement. For this reason, choices C) and E) are wrong.

Explanation:

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
