Answer:

<u>C</u>

Explanation:

Kinetic Energy formula :

<u>K.E. = 1/2mv²</u>

<u />

=============================================================

Given :

⇒ mass = 0.17 kg (needed)

⇒ distance = 20 m (not needed)

⇒ velocity = 22 m/s (needed)

============================================================

Solving :

⇒ K.E. = 1/2 × 0.17 × (22)²

⇒ K.E. = 11 × 0.17 × 22

⇒ K.E. = 1.87 × 22

⇒ K.E. = 41.14 ≈ <u>41 J</u>

Karolina [17]

Answer:

100% or 1

Explanation:

This question involves a gene coding for fur color in bears. According to the question, black fur allele (B) is dominant over the brown fur allele (b). This means that a bear heterozygous for fur color (Bb) will be phenotypically black.

In this question, a black father bear (genotype BB) and a brown mother bear (genotype bb) were crossed, the baby bears will all have a genotype Bb (see punnet square in the attached image). Since all the offsprings of this cross have genotype Bb, this means that 100% will have black fur.
