Answer:
a) 512.5 KW/m2
b) 40.75 KW/m2
c) 2 KW/m2
Explanation:
Given data;
T_2 = 325 K
T_1 = 275 K
dx = 0.20 mm
a) for aluminium K = 205 W/m k
heat flux 
= 512.5 KW/m2
b) for AISI 316 stainless steel
k = 16.3 W/ m k
heat flux
= 40.75 KW/m2
C) for Concrete
k = 0.8 W/ m k
heat flux
= 2 KW/m2
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.

Answer: its an Ignition coil
Answer:
Explanation:
So therefore new Resistance R¹ = R/49
Resistance of a wire
R = ¶ * L/A
Where ¶ = resistivity of wire
L = length of wire
A = cross sectional area of wire
So therefore if the wire is cut into 7 equal lengths and joined together to form one with new Resistance R¹
So new length L¹ = 1L/7
New A¹ = 7A
So therefore R¹ = ¶ (L/7) /(7A)
So R¹ = ¶*L/A(49)
Since R = ¶L/A
So therefore R¹ = R/49
