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.
: catalysing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another
To find the magnification you have to multiply the power of the objective by the power of the ocular
So the magnification would be 10x10= 100x
Answer:
1. Mistletoe is parasitic to the mesquite tree, it steals from the tree without giving anything valuable back to it. In this case, only the mistletoe gains an advantage.
2. If the mistletoe population on the tree were to increase, the mistletoe would probably end up slowly killing the tree. I say this because its a parasite to the tree. Its constantly stealing water and valuable minerals that it needs and doesnt give back anything that could help the tree. With all the water and minerals being stolen and an uneven rate with no way for the tree to replenish it all quickly enough it'll die.
3. Its parasitic since the mistletoe just takes and takes harmfully
D. living things in the biosphere.
The atmosphere contains all the air that plants and animals both use to survive so if there was a change within it, it would affect all living creatures in the biosphere.
