Answer:
3.63 meter/sec²
Step-by-step explanation:
When a rock fall from a height h with initial velocity u and the rock reaches the surface in t seconds the expression that represents this is 
h = 4t +  gt²
 gt²
Where g is the acceleration due to gravity
Here h = 0.72 meters
         u = 0
         t = 0.63 seconds
from the given formula
0.72 = 0 ×(0.63) +  g(0.63)²
 g(0.63)²
0.72 =  g(0.63)²
 g(0.63)²
g = 
= 3.63 meter/sec²
 
        
                    
             
        
        
        
Answer:
A,C,E
Step-by-step explanation:
A statistical question has variability in the answer, so,
A=could range from any numbers providing a wide range of results
B=it's one answer (eg.5ft4) meaning a range can't be produced
C=could range from any food providing a wide range of results
D=One answer so no variations possible
E= could be a range of numbers
