This picture shows a region where a flat plain meets a mountain. Two wildfires, A and B, just started in two different locations, If the wind is consistantly blowing from the west to the east, which fire will burn a greater amount of area in the next 12 hours? Wildfire A
Wildfire B
Both fires will spread at the same rate.

Explain your answer.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
