Answer:
B. 7.07 m/s
Explanation:
The velocity of the stone when it leaves the circular path is its tangential velocity,
, which is given by

where
is the angular speed and
is the radius of the circular path.
is given by

where
is the frequency of revolution.
Thus

Using values from the question,

<em>Note the conversion of 75 cm to 0.75 m</em>

Answer:
Yes
Explanation:
Each person has two alleles (forms of a gene) for a characteristic. We can represent them using letters.
Dominant trait are written as capitals. If a dominant allele is present in someone's genotype, the dominant trait will show.
The recessive trait only shows if a person has two recessive alleles.
Brown eyes is a dominant trait, and blue eyes is a recessive trait.
B = dominant brown eyes
b = recessive blue eyes
If someone has <u>brown</u> eyes, their genotype can be:
BB
Bb
If someone has blue eyes, their genotype is:
bb
The baby's genotype must be bb because it has blue eyes. <u>The baby gets one allele from each parent</u>.
See the photo for Punnett square. If the parents are both Bb, then they could each give the b allele, resulting in a blue-eyed baby.
Answer: B
<u>Explanation:</u>
E shows the direction of the ball but the question asks about the direction of the STICK, which is the opposite of the ball.
