<h2>Comparing kinetic energy of Boat A and B -Option 4 </h2>

Compared to the kinetic energy of Boat B, the kinetic energy of Boat A is nine times as much. Kinetic energy ( K.E ) is the energy which is possessed due to movement or motion. Its formula is 1 / 2 mv 2, there is square of velocity in terms of kinetic energy.

If the velocity of boat A is three times greater than that of boat B and the condition is both boats have the same mass so by putting values. Mass is constant and the square of velocity is ( 3 ) 2 = 9 therefore, 1 / 2 m ( 3v ) 2 = 1 / 2 m 9 v 2.

If we write it as 9 ( 1 / 2 m v 2 ) it means that kinetic energy of boat A is nine time as much.

A female rabbit of phenotype c’ is crossed to a male rabbit with c ch. The F1 is comprised of five rabbits with a c’ phenotype,
mojhsa [17]

Answer:

Option E, c is recessive to both c’ and c ch

Explanation:

As it is given in the question that when phenotypically c female rabbits are crossed with father with phenotype cch , the offspring produced have only cch phenotype which means that allele cch is dominant over allele “c”

Now in the F1 cross, when a female rabbit of phenotype c’ is crossed with cch male rabbit, then also c’ is expressed over “c” allele.  

Hence, c is recessive to both c’ and cch allele
