Question

What is the author's central idea in this text regarding recommended levels of insulation?

a) The importance of maintaining a specific angle in geometry
b) The application of substitution and subtraction properties in geometry
c) The significance of angle bisectors in geometry
d) The recommended levels of insulation for a given context

Answer 1

The author's central idea in this text regarding recommended levels of insulation is the recommended levels of insulation for a given context.

Step-by-step explanation:

The author's central idea in this text regarding recommended levels of insulation is d) The recommended levels of insulation for a given context.

The text emphasizes the importance of using appropriate values of C/1 by selecting the right radii of conductors and insulating material between them. This recommendation helps in limiting the conduction of heat between the inside and outside of a building.

For example, adding extra insulation in the attic of a house can significantly reduce heating and cooling costs. The thickness of the insulation plays a crucial role in determining the percentage of reduction in heating cost.
