Venn diagrams are used for comparing and contrasting topics. the overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics that apply to only that topic. this venn diagram is comparing mechanical and electromagnetic waves. what could be put into the center section of this venn diagram? “carry energy through space” and “follow a pattern” “carry energy” and “follow a pattern” “carry energy through space” and “can be heard” “carry energy” and “can be heard”

The commonality between the two waves is that they; “Carry energy” and “Follow a pattern”.

Hence, what is common is that all the waves carry energy.

To answer this question we need to know what both types of waves have in common. For them we describe the characteristics of each wave

Mechanical waves:

* Transport energy

* They need a means to spread (they do not spread through space)

* Only some of us can hear them

* They follow a pattern

Electromagnetic waves

* Transport energy

* They do not need a means to spread

* We can not hear them

* They follow a pattern

The characteristics that both have in common is that they transport energy (but in different mediums) and that they follow a pattern. Therefore, the correct option is:

"Carry energy" and "Follow a pattern"
