Rajus classmates should be educated on the dangers of bull_ying and the benefits of being kind instead.
<h3>What is bull_ying?</h3>
Bull_ying is an action which is directed to another individual due to real or perceived power imbalance to cause the individual fear or h_arm.
The dangers of bull_ying include:
- causes feeling of worthlessness in the individuals being bulli_ed 
- can lead to self_h_arm such as sui cide 
- bull_ies can be prosecuted.

Kinetic energy = 0.5*M*V^2 
 Q7-
 
0.5*3*(2^2)= 6J
Q8a- 
0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J 
the second ball has more kinetic energy.
Q8b-
at the max height, all the kinetic energy is converted to potential energy, 
gravitational potential energy is = M*g*h
that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:
First ball:
2kg*9.81(g)*10m = 196.2J
Second ball
4kg*9.81*10m= 392.4J
The second ball has more potential energy 
        
             
        
        
        
The difference between sharks and bony fish is that sharks have skeletons made up of cartilage and dont have bones, while bony fish have bones
 
        
                    
             
        
        
        
<u>Answer:</u>
Cyanobacteria start producing pure oxygen around 200 million years ago.
<u>Explanation:</u>
Many scientists believed that Earth did not have any oxygen. Cyanobacteria or the blue green algae are the microbes which produced oxygen for the first time with the help of photosynthesis.  This was around 4.5 billion years ago: after Hadean eon.
They were very simple, but they produced oxygen in the early earth’s atmosphere. So, they brought evolution on earth. This “blue-green algae” exists in salt water, rocks and soils and play a major role in maintaining the ecosystem.
 
        
                    
             
        
        
        
Answer:
law of independent assortment
Explanation:
Independent assortment is the random distribution of the pairs of genes on different chromosomes to the gametes.  I hope this helps :)
