What was your electric potential relative to a metal pipe if a spark jumped 1.1 cm through dry air from your finger to the pipe?

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

Ball bearings are made by letting spherical drops of molten metal fall inside a talll tower-called a shot tower- and solidify as they fall. a-if a bearing needs 4.0 s to solidify enough for impact, how high must the tower be? b- what is the bearing's impact velocity?

Asign is hung between two cables as illustrated below. if the sign weighs 350 n, what is the tension (in n) in each cable?
