The density of the material would be 
25/6 grams per cm^3.
to obtain the result above this is what we do:
density is calculated as: (the mass of the given material or object) / volume of the material 
which leads us to 50grams /12cm^3
 
        
             
        
        
        
In the reaction between 1 molecule of bromine and 2 molecules of potassium chloride, there are six atoms in the products.
Let's consider the balanced equation for the reaction between 1 molecule of bromine and 2 molecules of potassium chloride. This is a single replacement reaction.
Br₂ + 2 KCl ⇒ 2 KBr + Cl₂
We obtain as products, 2 molecules of potassium bromide and 1 molecule of chlorine.
- 1 molecule of KBr has 2 atoms, so 2 molecules contribute with 4 atoms.
- 1 molecule of Cl₂ has 2 atoms.
- The 4 atoms from KBr and the 2 atoms from Cl₂ make a total of 6 atoms.

Answer:
T= 38.38 N
Explanation:
Here
mass of can = m = 3 kg
g= 9.8 m/sec2
angle θ = 40°
From figure we see the vertical and horizontal component of tension force T
If the can is to slip - then horizontal component of tension force should become equal to force of friction.
First we find force of friction
Fs= μ R
where
 μ = 0.76
R = weight of can = mg = 3 × 9.8 = 29.4 N
Now horizontal component of tension 
Tx= T cos 40 = T× 0.7660  N
==>T× 0.7660 = 29.4
==> T= 38.38 N
 
        
             
        
        
        
Answer:
0.015 m/s2
Explanation:
Using Newtons 2nd law.
F = ma where F = Force applied, m = mass of the object and a = acceleration acquired.
So substitute the values in SI units.
 m =  kg
 kg
Therefore F = 0.003×5 = 0.015 m/s2
 
        
             
        
        
        
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.
