Answer:
Change in velocity: yes
Change in acceleration: no
Explanation:
The diagram of the problem is missing: find it in attachment.
In the diagram, there are represented:
- The velocity of the car, as a vector labelled with V
- The acceleration of the car, as a vector labelled with A
The directions of the vector represent the direction of the velocity and the acceleration, while the length of the arrows represent the magnitude of the two quantities.
We observe that:
- For the velocity, the direction is always to the right; however, the length of the arrow decreases, so the magnitude of the velocity keeps decreasing
- For the acceleration, the direction is always to the left; and the length of the arrow remains constant, therefore the magnitude of the acceleration does not change.
This means that the car is moving to the right, but it is slowing down, since the direction of the acceleration is opposite to the direction of the velocity.
Answer:
50%
Explanation:
This question involves a gene coding for eye color in humans. The allele for brown eyes (B) are dominant to blue eyes (b). This means that blue-eyed individual will possess genotype: bb.
According to this question, a blue-eyed man (bb) has children with a brown-eyed woman (B_) whose mother has blue eyes (bb). Since the mother of the brown-eyed woman has a blue eye, this means that the woman will be heterozygous for brown eye (Bb).
Hence, the parents in this question will cross as follows: blue eyed man (bb) × brown-eyed woman (Bb). The offspring/children will have the following genotypes (see attached punnet square); Bb, Bb, bb, bb.
Based on the question, 2/4 = 1/2 of the children will be heterozygous for the eye color trait. That is, ½ × 100 = 50%.
