Which characteristic are shared by electromagnetic and mechanical waves? check all that apply. a. both have a crest and a trough b. both move due to particles bumping into each other c. both can move through matter d. both can occur as a result of a disturbance e. both are formed by charged particles

The answers would be the following:

A. both have a crest and a trough

C. Both can move through matter

D. Both can occur as a result of a disturbance.

For choices A and D, these are characteristics of ALL types of waves. The crest is the highest point of a wave and a trough is the lowest point of a wave. The definition of a wave is a disturbance that transfers energy from one point to another.

Now for B, both can move through matter. The main difference between these two is that mechanical waves move through matter generally, or they cannot occur without a medium. Electromagnetic waves on the other hand can move through matter but it can also move through empty space.

The characteristic shared by electromagnetic and mechanical waves is A, C and D.

Explanation:

Electromagnetic wave is the transverse wave. It is produced by the moving charged particle. In the electromagnetic wave, the electric field and the magnetic field are perpendicular to each other. It consists of a crest and a trough. It does not require a medium to travel.

In mechanical wave, there is an oscillation of matter. It requires a medium to travel. The three types of mechanical waves are longitudinal wave, transverse wave and surface wave.

Therefore, the characteristic shared by electromagnetic and mechanical waves is

A both have a crest and a trough.

C both can move through matter.

D both can occur as a result of a disturbance.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
