Explanation:
The runner runs for a total time of
\Delta t=10.0 min= 600 sΔt=10.0min=600s
The energy converted by the runner during this time is equal to the power of the runner times the total time:
E=P \Delta t=400 W \cdot 600 s =2.4 \cdot 10^5 JE=PΔt=400W⋅600s=2.4⋅10

Answer: live conductor with his right hand and touches a ground with his left hand
Explanation:
When a technician touches a live conductor with his right hand and touches a ground with his left hand, it is the most dangerous, and likely to cause serious injury.
This is because when the person touches the live conductor, there will be an electrical path which will allow current flow with the aid of the person's body. This is because the body of human being is a conductor. Therefore, when the technician touches the live conductor with his right hand and touches a ground with his left hand, an electrical path is created.
