Effect of temperature.
"If the temperature of the substance is increased then the rate of chemical reaction is also increased because the kinetic energy is greater."
Effect of surface area.
"If the surface area is increased then the rate of reaction is increased because there will be more active sites for the reaction to occur. 
        
                    
             
        
        
        
Answer:
 d = <23, 33, 0> m
,    F_W = <0, -9.8, 0>
,   W = -323.4 J
Explanation:
We can solve this exercise using projectile launch ratios, for the x-axis the displacement is
          x = vox t
Y Axis  
          y =  t - ½ g t²
 t - ½ g t²
It's displacement is
       d = x i ^ + y j ^ + z k ^
Substituting
       d = (23 i ^ + 33 j ^ + 0) m
Using your notation
    d = <23, 33, 0> m
The force of gravity is the weight of the body
          W = m g
         W = 1  9.8 = 9.8 N
In vector notation, in general the upward direction is positive
          W = (0 i ^  - 9.8 j ^ + 0K ^) N
          W = <0, -9.8, 0>
Work is defined
            W = F. dy
              W = F dy cos θ
In this case the force of gravity points downwards and the displacement points upwards, so the angle between the two is 180º
           Cos 180 = -1
            W = -F y
            W = - 9.8 (33-0)
            W = -323.4 J
 
        
             
        
        
        
Hypothesis testing is basically testing the results of a experiment to see weather your results are valid or not.
