If 5 x 1016 electrons pass across the section of a conductor in 80 seconds. The intensity of flowing current is ... (charge of electron = 1.6 x 10-19 C) C

c.the charges if the proton and electron and gravity

less than one you can't create energy

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.)
