Alightning strike consists of charge moving from a cloud to the ground . in one particular case, the electrons in a lightning strike are confined to travel within a radius of 1.5 m and to move at a speed of 5.0 x 10 m/s. if the density of electrons in the strike is 10'15 electrons/m what current is carried by the lightning ?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

How do you tell if someone actually cares about you? and just say they do?
