Astraight wire carries a 12-a current eastward and a second straight wire carries a 14-a current westward. the wires are separated by a distance of 42 cm. the force on a 6.4 m length of one of the wires is

Explanation:

The force exerted between two current-carrying wires is given by

where

is the vacuum permeability

I1 and I2 are the two currents

L is the length of the segment of wire on which we want to calculate the force

r is the distance between the wires

In this problem we have:

Substituting into the formula, we find:

And since the direction of the two currents is opposite, the force between the wires is repulsive.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
