Question
Need help with #1 and #2 Part, thanks!
Transcribed Image Text:Measurements made during severe electrical storms reveal that
lightning bolts can carry as much as 30 C of charge and can travel
between a cloud and the ground in time intervals of around 100 μs
(and sometimes even shorter). Potential differences have been
measured as high as 400 million volts.
