Answer:
36.87 km/h
Explanation:
Convert all the units in SI system 
1 mile = 1609.34 m
d1 = 6 mi = 9656.04 m
t1 = 15 min = 15 x 60 = 900 s
d2 = 3 mi = 4828.02 m
t2 = 10 min = 10 x 60 = 600 s
d3 = 1 mi = 1609.34 m 
t3 = 2 min = 2 x 60 = 120 s 
d4 = 0.5 mi = 804.67 m
t4 = 0.5 min = 0.5 x 60 = 30 s
Total distance, d = d1 + d2 + d3 + d4 
d = 9656.04 + 4828.02 +  1609.34 + 804.67 = 16898.07 m = 16.898 km
total time, t = t1 + t2 + t3 + t4 
t = 900 + 600 + 120 + 30 = 1650 s = 0.4583 h 
The ratio of the total distance covered to the total time taken is called average speed. 
Average speed = 16.898 / 0.4583 = 36.87 km/h

Answer:
(A) ratio of electric force to weight will be  
(b) Electric field will be 
Explanation:
We have given mass of bee = 100 mg  = 
Charge on bee 
Electric field E = 100 N/C
Weight of the bee 
Electric force on the bee 
So the ratio of electric force on the bee and weight is 
(B) To hold the bee in air electric force must be equal to weight of bee 
So 


 
        
             
        
        
        
Answer:
0.012 J
Explanation:
We are given:
q = 0.0080C
Potential difference =  1.5V
W=qV
Substituting the values into the equation:
W=0.0080*1.5= 0.012J
