A copper telephone wire has essentially no sag between poles 36.0 m apart on a winter day when the temperature is −20.0°C. How much longer is the wire on a summer day when the temperature is 34.0°C?

The extension is  

Explanation:

From the question we are told that  

     The length of the wire on a winter day is    

      The temperature on the winter day is  

      The temperature on a summer day is  

The the extension of the wire on a summer day is mathematically represented as

Where  

      is the  coefficient of linear expansion of copper with a values

substituting value  

increase masses, decrease separation

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.
