Answer:
Explanation:
According to work energy theorem 
change in kinetic energy of truck = work done against it 
work done against it = force x displacement 
= - 850 x 8 = 6800 J 
change in kinetic energy of truck = - 6800 J . 
energy will be reduced by 6800 J 
 
        
             
        
        
        
Answer:
- increasing use of hybrid crops
- altering genes in DNA to create new plants
- developing disease or pest resistant crops
Explanation:
The use of genetic factors to influence the growth of a plant encompasses manipulating the genetic constituent (gene) of such plant. 
For example, 
- Increasing use of hybrid crops entails mating two pure bred plants based on a gene of interest responsible for a particular trait, to form a hybrid. 
- Altering genes in DNA to create new plants is also a genetic factor as it has to with gene modification. 
- developing disease or pest resistant crops means that the genetic make up of such plant has been modified to be resistant to pest/disease. 
 
        
             
        
        
        
Answer:
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. ... Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.
