Answer:
Interference
Explanation:
When two traveling waves traveling waves along the same path are superimposed(combine). The superimposition of these two waves results in the production of a resultant wave which is defined by the net effect of the two waves. Wave interference occurs most types of waves including radio wave, light, acoustic waves and other wave types. Alternating sound between loud and Zero is heard as the two speakers emit identical pure tones because the resultant amplitude after the interference of the two sound waves is the vector sum of each of their amplitudes. A loud sound is heard, when the crest of both waves meets each other and a zero is heard if the crest of one meets the trough of the other as they cancel out.
The sun has orbited along time so when they ask theses questions I give you the right answer I think lol
<span>Sound waves with frequency higher that 20,000 Hz are referred to as "Ultrasonic"
Hope this helps!</span>
<span>Notice for the Carbon question they were the same element and the shared the same number of protons. so i think d. is the answer</span>
Run electrity through or is postive to the circuit
