Given the differential equation, what does the temperature profile vary with? (c is a constant)

• T(x) = f(-x², cx)

• T(x) = f(cx)

• T(x) = f(-x²)

• T(x) = f(-x², ln(x))

Given the differential equation, what does the temperature profile vary with? (c is a constant)

• T(r) = f(-r², ln(r))

• T(r) = f(-r²)

• T(r) = f(ln(r))

• T(r) = f(cr)

What is the net radiative heat transfer between the surface and the surroundings?

• 100 W/m²

• 10 W/m²

• 94.2 W/m²

• 50 W/m²

What is the heat transfer from the sun to the surface?

• 1000 W/m²

• 50 W/m²

• 900 W/m²

• -50 W/m²

Considering the surface absorbs 50 W/m² from the sun and loses 100 W/m² to the surroundings, what is the heat generation required if the surface is 0.1 m thick?

• q''' = 50 W/m²

• q''' = 500 W/m³

• q''' = 50 W/m³

• q''' = 5 W/m³
