balandron [24]3 years ago
8 0

Answer:

When they slide down, they lose this potential energy, which turns into kinetic energy and thermal energy. Thermal Energy - This energy is related to the temperature of a body or a system. When friction is involved in a system, part of the kinetic energy is transformed into thermal energy.

Lemur [1.5K]

Answer:

q = 0.42

Explanation:

This question is an example of Hardy-Weinberg question and there are two equations necessary to carry out this question;

p + q = 1

p² + 2pq + q²  = 1

where;

p = the frequency of the dominant allele

q =  the frequency of the recessive allele

p² = the frequency of individuals with homozygous dominant genotype

2pq  = the frequency of individuals with heterozygous genotype

q² = frequency of individuals with the homozygous recessive genotype

Since the total  population = 425

q² = \frac{individuals with recessive genotype}{Total Population}

= \frac{75}{425}

q² = 0.1765            

To find q; we need to square root both side to           eliminate the square from  q².

∴ \sqrt{q^2}=\sqrt{0.1765}

q = 0.4201

q = 0.42       (to two decimal places)
