Explanation:
The phenomenon of superimposing of two waves such that the resultant wave have greater, lower, or the same amplitude.
There are two conditions for the interference.
- Constructive wave interference: This type of interference occurs after adding of two maxima such that the amplitude of the resulting wave is equal to the sum of the amplitudes of individual waves.
- Destructive wave interference: In this type of interference, the amplitude of the resulting wave gets reduced as the crest of one wave meets with the trough of another wave.
Answer:
7.60× 10^6 V/m
Explanation:
electric field strength can be determined as ratio of potential drop and distance, I.e
E=V/d
Where E= electric field
V= potential drop= 74.0 mV= 0.07 V
d= distance= 9.20 nm = 9.2×10^-9 m
Substitute the values
E= 0.07/ 9.2×10^-9
= 7.60× 10^6 V/m
Answer:
d) AN (article accession number)
Explanation:
APA format is commonly found in term papers, essays, and scientific papers. It consists of an in-text citation with a reference list to accompany it. The writer needs to cite the author and year of the work by putting them in parentheses separated by a comma (Author's name, year), for the references list the pattern is author, date, title, source. This format suffers small modifications depending on the kind of document you want to cite, for example, for a scholarly journal article te format is:
Author or authors (surname is followed by first initials). Year of publication of the article (in round brackets). Article title. Journal title (in italics). Volume of the journal (in italics). Issue number of the journal in round brackets (no italics). Page range of article. DOI.
An example is annexed as an image at the end.
<em>Therefore AN (article accession number), sometimes called a Document ID, is a unique number assigned by a particular database as an additional means of locating a specific article, this number is distinct and unrelated to a document’s DOI number, is NOT included in an APA citation for a scholarly journal article.</em>
