The first distance covered westward is
=>
=>
For the second question eastward is in the direction of the positive x-axis so it would be positive and westward is in the direction of the negative x-axis so it would be negative

Answer:
The fatel voltage is 100 volts.
Explanation:
Given that,
Current passes near the heart is,
An electrician working with sweaty hands makes good contact with the two conductors he is holding, one in each hand.
Resistance, R = 2000 ohms
We need to find the fatal voltage. It can be calculated using Ohm's law as :
So, the fatel voltage is 100 volts. Hence, this is the required solution.
