The statement is false. The truth is just the opposite. The presence of easily-moved electrons makes it a good conductor.
Answer: your answer is waves.
I will type random words cause my answer is “too short”: dnuidnuindudnnnudinnndijndiudnnnndnijndjidnjidnijdnijdnnnndnjidnjidnnn
Note : Be careful with speed and velocity, even the formula is same that
1. If we would like to find the velocity, we must calculate the distance from initial to final,
,
2. If we would like to find the speed, we must calculate the total distance that travelled (
.
So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.
I don't think so, because in order to produce an image, you need a surface behind the mirror. The light will hit the mirror, then it will bounce it back in your eyes and you see the image.
I think the answer is d. The circulatory system carries chemical signals from your endocrine system that control the speed of digestion.
