Answer:
E = 0.0130 V/m.
Explanation:
The electric field is related to the potential difference as follows:

<u>Where:</u>
E: is electric field 
ΔV: is the potential difference = 3.95 mV  
d: is the distance of a person's chest = 0.305 m
Then, the electric field is:

Therefore, the maximum electric field created is 0.0130 V/m.
I hope it helps you!
 
        
             
        
        
        
Answer:
1.a) 1 kJ
1.b) 4 kJ 
      ratio 1:4
1.c) 4 times as before
2.a)  3.33 m/s2
Explanation:
1.a) bicycle's velocity =Displacement/time
                                    =100/20 m/s
                                    =5 m/s
bicycler's KE =1/2 *mass*(velocity)^2
                       =1/2*80*5^2
                        =1000 J = 1 kJ
1.b) bicycle's new velocity =200/20 m/s
                                    =10 m/s
bicycler's new KE =1/2*80*10^2
                              =4000 J = 4 kJ
Ratio= KE 1 :KE new
         = 1 :4 
1.c)  when bicycler's speed was doubled it increased the KE by 4 times (2^2). because In KE we consider the square of the speed , so the factor we increase the speed , the KE will get increased with the square value of it
ex : speed is triple the prior value , then the KE is as 3^2 times as before. that is 9 times
2.a) car acceleration = (20-0)/6 m/s2
                                   = 3.33 m/s2
