Answer:
The question is incomplete, the complete question is:
Which of the following is not a reason to give yourself extra "cushion" when driving?
A. Poor visibility B. Poor road conditions C. Inclement weather D. None of these.
The correct answer is D. None of these.
Explanation:
All the options are not reasons to give yourself an extra cushion when driving, rather they are reasons that are not favorable to driving at all.
A cushion is a certain amount of distance you are supposed to keep between you and the car in front of you to allow easy maneuvering in any condition.
A typical cushion is 3 seconds between you and the car in front of you, in less than perfect conditions like bad weather or poor road conditions an additional second must be added to it.
The quantity heat loss through below-grade basement walls at a depth of 6-7 feet with no insulation is C. 0.069
<h3>What is insulation?</h3>
Insulation is the process of constructing a barrier between two objects that reduces heat transfer by either reflecting thermal radiation or decreasing thermal conduction and convection from one to the other. The insulation will be more or less effective depending on the material of the barrier.
We can directly see the value of heat loss below grade basement walls at different depth from the handbook of fundamentals.
Heat loss through below grade basement walls at depth of 6-7 ft with no insulation is
= 0.069 BTU/hr.ft.0F (In English units)
Hence option ( C ) is correct.

True
the answer to this would be true
Answer:
material is aluminum by the approx value of conductivity
Explanation:
given data
length = 3 km
temperature = 20 °C
metallic wire = AWG-6
resistance = 6Ω
to find out
What material is it made of
solution
we know that AWG - 6 has a diameter of 4.1 mm
so we know resistance R is
R =
here A is area and R is resistance and l is length so find here σ
σ =
σ =
σ = 3.79 × S/m
so according to table 2-1
material is aluminum by the approx value of conductivity
