Your boss asks you to design a room that can be as soundproof as possible and provides you with three samples of material. The o

nly information on each sample's label is the material's coefficient of absorption. The coefficient of absorption listed on Sample A is 30%, on Sample B is 47%, and on Sample C is 62%. When your boss asks for your choice and the reasoning behind it, what would you tell him? A. Sample C would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the largest. B. Sample A would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest. C. Sample A would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the largest. D. Sample C would be best, because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest.

Answer: Sample C is 62%.

Sample C would be best because it has the highest coefficient of absorption. <span>Sound absorption coefficient is defined as THE ratio of absorbed energy to incident energy and the higher the percentages, the better the absorption is. It indicates that most of the sound being absorbed and less is being reflected back. </span>

is a recessive,hereditary disease that is life threatening because of overproduction mucus in vital organs such as the lungs
user100 [1]

The cystic fibrosis is a condition, in which the secretion of mucus in some vital organs such as lungs, pancreas, and stomach becomes sticky and thick.

This condition is caused by the inheritance of the recessive gene responsible for the development of the cystic fibrosis.

The thick and the sticky mucus gets lined up on the walls of the organ and causes the clogging of the tubes and the ducts, hence, instead of providing lubrication they act as clogging agent and causing major damage to some vital organs, especially, lungs and the pancreas.
