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.
Hey, sorry about the person who gave you a virus... pretty sure most people who leave links are doing similar things unfortunately. The answer is Archaebacteria I’m pretty sure. Eubacteria are found everywhere, Fungi are mushrooms, protists exist all over underwater areas. Haven’t researched it in a while but hope this answer helps :)
The phospholipid no later regulates the amount of water that travels in and out of the cell.
