Answer:
0.002833 sec
Explanation:
Speed of light in vacuum is
Given distance = 850 km = 850×1000=850000 m
We have to calculate the time that light take to travel the distance 850 km
Time
So the time taken by light to travel 850 km is 0.002833 sec
As the resistance increased under 25 V, the current blank. Compared to calculated currents, experimental currents proved to be b
