Answer: the reaction
Explanation: it’s the only answer that is the result
The correct answer is letter C. The angle of incidence is equal to 55 degrees. This is because Specular Reflection refers to mirror-like reflection of light or other kinds of waves from a surface. This phenomenon is where light from a single incoming direction is also reflection in a single-outgoing direction.
All of the above

Answer:
Q= 231.88 W/m²
Explanation:
Given that
L= 20 cm
K= 2.79 W/m·K
T₁=50°C
T₂= 22°C
h=15 W/m₂·K
The total thermal resistance
Now by putting the values
R= 0.138 K/W ( for heat flux A= 1 m²)
Heat flux Q= ΔT/R
Q= (50-22)/0.138 = 32/0.138 W
Q= 231.88 W/m²
Answer:
