Answer:
c. predation, competition, parasitism
Explanation:
The important and only biotic factors from the given choices that can affect the structure and organization of biological communities are predation, competition and parasitism.
These factors ensures that there are interaction between organisms of the same and different species and only occur in life.
Biotic factors are the living component of the ecosystem that dictates what happens therein.
- Predation is an interaction between two organisms in which the predator, bigger organism feeds on the prey, smaller organism.
- Competition occurs where two organism of the same or different species struggles for limited resources in the ecosystem.
- Parasitism is an interaction where one organism feeds on the another and it causes harm to it. The organism feeding on another is called the parasite. And the one it is dependent on is the host.
All of these are biotic factors.
The side B will fall down so that means the rope will move the direction of A
Sn is in group 4 so has 4 electrons in the outer shell (draw<span> these as dots) Add 1 more electron from each bond to F (+6) </span>
To solve this problem it is necessary to use the conservation equations of both kinetic, rotational and potential energy.
By definition we know that
Where,
KE =Kinetic Energy
KR = Rotational Kinetic Energy
PE = Potential Energy
In this way
Where,
m = mass
v= Velocity
I = Moment of Inertia
Angular velocity
g = Gravity
h = Height
We know as well that 
for velocity (v) and Radius (r)
Therefore replacing we have
![[tex]h= \frac{1}{2} \frac{v^2}{g} +\frac{1}{2} \frac{I}{mg}(\frac{v}{r})^2](https://tex.z-dn.net/?f=%5Btex%5Dh%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Cfrac%7Bv%5E2%7D%7Bg%7D%20%2B%5Cfrac%7B1%7D%7B2%7D%20%5Cfrac%7BI%7D%7Bmg%7D%28%5Cfrac%7Bv%7D%7Br%7D%29%5E2)

Therefore the height must be 0.3915 for the yo-yo fall has a linear speed of 0.75m/s
You can not determine the speed based on the information given
