question 7 of 10
which three characteristics do mechanical waves and electromagnetic waves share?
a. the waves transfer energy from its source.
b. the waves begin with a disturbance.
c. the waves and their energy move outward from the source.
d. the waves and their energy can travel through empty space.

Explanation:

Both mechanical and electromagnetic waves transfer energy from a source, start with a disturbance, and move outward from the source. Mechanical waves need a medium and can't travel through empty - space, while electromagnetic waves can. So D is incorrect.
