Alightning bolt carrying 30,000 a lasts for 50 micro-seconds. if the lightning strikes an airplane flying at 20,000 feet, what is the charge deposited on the plane?

1.5 Columb charge is deposited on the plane.

Explanation:

The relationship between charge and current is:

Current = Charge/Time

Therefore,

Charge = Current x Time

We have,

Current = 30,000 A

Time = 50 micro-seconds = 50 x 10^(-6) sec

Using these values:

Charge = [30,000 A][50 x 10^(-6)]

Charge = 1.5 C

b would be the answer

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
