Answer:Mass of bullet, m=20g= 0.02kg
Velocity of bullet, v=100m/s
Mass of gun, M=5kg
Let recoil velocity of gun =V
Before firing, the system (gun+bullet) is at rest, therefore, initial momentum of the system =0
Final momentum of the system = momentum of bullet + momentum of gun
=mv+MV=
=2+5v
we know Final momentum = Initial momentum
i.e., 2+5v=0
5V=−2
v=-0.4m/s
Negative sign shows that the direction of recoil velocity of the gun is opposite to the direction of the velocity of the bullet.
The cell cycle or cell division cycle is the M phase it self compounded of two mitosis is the process by which a eukaryotic cells cycle is also divided into three periods interphase The mitotic (m) phase and cytokinesis. During interphase, the cell grows
<span>Quantitative data refers to data that is in numerical form and can be counted or quantified. Quantitative data can be put through statistical analysis tests. It usually requires interpretation by researchers and can be paired with qualitative data.</span>
Answer:
It affects populations, It occurs when there is genetic variation, It selects organisms with certain traits to survive. I'm not 100% sure this is completely correct, but I just studied this in school and this sounds right. :)
Answer:
b. Craig is right and doesn't have to pay child support.
Explanation:
ABO blood group is controlled by three alleles. IA and IB are codominant to each other and both are dominant over i allele. IAIA and IAi produce A blood group. IBIB and IBi produce B blood group. ii produces O blood group.
Susan's son has O blood group so his genotype must be ii. He got one "i" allele from Susan and one "i" allele from his father. Craig's genotype is IAIA so there is no chance that he could have passed on "i" allele to Susan's son. Hence Craig is not his father and does not need to pay child support.
