Answer:
Option A
Explanation:
As we all know, energy can never be created . Also it can never be destroyed. However, it can only be changed from one form to the other. In this case, when a pool ball is striked by a stick, the kinetic energy of stick is transferred to the ball along with release of sound. Sound is just another form of energy.
Now, when this ball strikes other balls, the same process is repeated i.e the ball strikes another ball and passes on its kinetic energy along with release of sound energy. Every time sound is released, the amount of kinetic energy transferring from one body to other reduces.
Option A is correct
Answer:
Low validity and low reliability.
Explanation:
Structured interview may be defined as a type of interview in which the interviewer has already decided the question. The questions are asked in the same series during the interview.
Diagnostician A has classified the individual as “odd” cluster. The Diagnostician B classifies an individual's personality as“dramatic” cluster. The structured interview has low reliability. The structured interview has low validity also as compared with other type of interview.
Answer: 9:3:3:1.
A cross between two plants that are heterozygous green and heterozygous tall is completed. What is the phenotypic ratio? The phenotypic ratio for the problem above is 9:3:3:1. Note that when crossing two heterozygous (for both alleles) parents this will always be the ratio.
