The first one, or A. You can tell because a dominant allele is capital, and a mixed allele (can't remember the technical term). or Aa, still would show dominant traits. So if short hair is dominant, due to long hair being recessive, a punnet square showing GG, Gg, Gg, and g, has 3 out of 4 showing dominant traits.
Hope I helped!
Answer:
Explanation:
Incomplete question but for understanding.
We want to find the electrical force between two charges, then you can use the coulombs law which states that the force of attraction or repulsion between two charges is directly proportional to the product of the two charges and inversely proportional to the square of their distance apart,
So,
F = kq1•q2 / r²
Where k is a constant and it is given as
K = 8.99 × 10^9 Nm²/C²
q1 and q2 are the charges and in this question it is not given, so the question is incomplete. Let assume that,
q1 = - 1.609 × 10^-19 C electron
q2 = 1.609 × 10^-19 C proton
Since unlike charges attract, then it is force of attraction
Also, r is the distance apart and it is not given, let assume the distance between the two charges is 2 × 10^-5m
Then,
F = kq1•q2 / r²
F = 8.99 × 10^9 × 1.609 × 10^-19 × 1.609 × 10^-19 / (2 × 10^-5)²
F = 5.82 × 10^-19 N
Answer:
45000 Kg.m/s
Explanation:
change in momentum = m( v¹-vi)
=3000(25-10)
= 45000
Answer:
i don't know how to explain it but I think it's just the way you do it by yourself
Velocity increases with speed
