Answer:
91.017N
Explanation:
Parameters
L=4.67m, m=0.192kg, t = 0.794s, The pulse makes four trips down and back along the cord, we have 4 +4 =8 trips( to and fro)
so N= no of trips = 8, From  Wave speed(V) = N *L/t , we have :
V= 8*4.67/0.794 = 47.0529 m/s.
We compute the cords mass per length,  Let it be P
P = M/L = 0.192/4.67 = 0.04111 kg/m
From  T = P * V^2  where T = Tension, we have
 T = 0.04111 * (47.0529)^2
 T =  91.017N. 
The tension in the cord is 91.017N
 
        
             
        
        
        
Atmospheric electricity and storms,electric current in a vacuum,spark discharge,electrostatic control filters and industrial electrostatic  separation <- those are just a few
