Answer:
0.8764kgm/s
Explanation:
Finding the velocity(v) before it hits the ground , where g is 9.8m/s²
v²= u² + 2gh
v² = 0 + 2× 9.8 × 2
v² = 40
v = √39.2
=6.26m/s
momentum= mass × velocity
= 0.14 × 6.26
= 0.8764kgm/s
Answer:
It's wrong.
Explanation:
In the Punnett square, we will use F to represent the dominant freckles gene and f to represent the recessive lack-of-freckles gene. The first individual would have FF, because homozygous means that both alleles are the same. The second individual would have Ff, because heterozygous means that it has 2 different alleles. If the first individual passes down one of its "F" alleles and the second individual passes down its "F" allele, the offspring would have 2 dominant alleles, and the researcher's conclusion is disproven.
