Question

Electric cables hang loosely from the poles during summer but do not appear so in winter.
Why?

Answer 1

Electric cables expand due to the application oh heat.During summer therefore they are loosely attached to the poles for sufficient expansion.During winter due to the application of cold they contract.Therfore they do not appear so in winter.

Answer 2

Electric cables hang loosely during summer due to the expansion process and they contract during winter due to the contraction process.

Explanation:

• Electric cables are the solids which exhibit the property of contraction and expansion.
• During the summer season, the solids will have their atoms in a free flow which leads to a slight expansion process.
• While in the case of the winter season, the solids will contract due to the inert pack of the molecules or atoms within the solids
