Answer:
Here are some examples of tropism in plants : Sunflowers are one of the best examples of positive phototropism , as they always grow facing the sun. 
Explanation:
 Although some experts consider that perhaps such a clear growth movement should not be considered tropism.
 
        
             
        
        
        
Work done is the distance a force acts over. 
So, the work done here is 9.0N * 3.0m = 27 J
        
                    
             
        
        
        
<span>F x L = W x X whereW=weight is total load = 80, L is length from fulcrum which is the unknown and what we are solving for. x= length we know. and F equals 50 force we know. So (W*X)/F=LL equals 64</span>
        
             
        
        
        
They cause an increase in temp of earths atmosphere or warming by absorbing solar energy. hope this helps
        
             
        
        
        
Answer:
No. of Neutrons = 3 
Explanation:
The atomic number of Lithium is given as 3 in the symbol while the mass number is given as 5.941 which is approximately equal to 6.
Mass Number = No. of Protons + No. of Neutrons = 6
Atomic Number = Number of Electrons = No. of Protons = 3
Therefore,
Mass Number - Atomic Number = (No. of Protons + No. of Neutrons) - No. of Protons
Mass Number - Atomic Number = No. of Neutrons
No. of Neutrons = 6 - 3
<u>No. of Neutrons = 3 </u>
