Find the ratio of the diameter of aluminium to copper wire, if they have the same resistance per unit length. Take the resistivity values of aluminium and copper to

be 2.65× 10−8 Ω m and 1.72 × 10−8 Ω m respectively​

1.24

Explanation:

The resistivity of copper

The resistivity of Aluminum,

The wires have same resistance per unit length.

The resistance of a wire is given by :

According to given condition,

So, the required ratio of the diameter of Aluminum to Copper wire is 1.24.

we need to know the time interval during which the force acts. impulse of force = momentum change

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
