Answer:

Super insulation are obtained by using layers of highly reflective sheets separated by glass fibers in an vacuumed space. Radiation heat transfer between any of the surfaces is inversely proportional to the number of sheets used and thus heat lost by radiation will be very low by using these highly reflective sheets which will an effective way of heat transfer.

14. The maximum amount a homeowner should spend on housing is
Simora [160]

Answer:

28%

Explanation:

Although there are sources that says 30% of gross income can be spent on housing, the most reliable amount that can be spent (according to other sources) is 28%.

Take for instance, you earn $5000 monthly, the maximum that you can spend on housing is:

Max = 28\% * \$5000

Using a calculator, we have:

Max = \$1400

<em>The maximum that can be spent on a monthly gross income of $5000 is $1400</em>

dybincka [34]

Answer:

The code is attached.

Explanation:

I created a string s including 6 colors with spaces in between. Then I converted the string into a list x by using split() method. I used three different methods for removing elements from the list. These methods are remove(), pop() and del.

\\ Then I used methods append(), insert() and extend() for adding elements to the list.

\\ Finally I converted list into a string using join() and adding space in between the elements of the list.
