6) Explain Newtons formula for velocity of sound. What is its limitation?
Answers
Explanation:
Answer. Hence putting the values of the atmospheric pressure and density of air , speed of sound in air was coming to 279.5m/s. This was the limitation in Newton's formula for velocity of sound. Now putting the values, v air=approximately 330m/s
Answer:
The nucleoid (meaning nucleus-like) is an irregularly shaped region within the prokaryotic cell that contains all or most of the genetic material.[1][2][3] The chromosome of a prokaryote is circular, and its length is very large compared to the cell dimensions needing it to be compacted in order to fit. In contrast to the nucleus of a eukaryotic cell, it is not surrounded by a nuclear membrane. Instead, the nucleoid forms by condensation and functional arrangement with the help of chromosomal architectural proteins and RNA molecules as well as DNA supercoiling. The length of a genome widely varies (generally at least a few million base pairs) and a cell may contain multiple copies of it.
