In a lightning bolt, a large amount of charge flows during a time of 1.4 x 10-3 s. Assume that the bolt can be represented as a long, straight line of current. At a perpendicular distance of 37 m from the bolt, a magnetic field of 7.8 x 10-5 T is measured. How much charged has flowed during the lightning bolt?

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
