Final answer:
The equation h(Ts - T∞) = -k · ∆y pertains to the relationship between conduction in solids and convection in fluids in the field of Physics, specifically in heat transfer. The correct option for the relationship described by the equation is 'Convection in the fluid = Conduction in the solid'. Therefore, the correct option is a).
Step-by-step explanation:
The equation h(Ts - T∞) = -k · ∆y mentioned in the student's question appears to be related to heat transfer, and more specifically, to the relationship between conduction in a solid and convection in a fluid. In Physics, heat transfer is a topic that encompasses different mechanisms such as conduction, convection, and radiation.
For conductive heat transfer, the equation typically used is Q/t = kA(T2 - T1) / d, where Q/t is the rate of heat transfer, k is the thermal conductivity of the material, A is the surface area, d is its thickness, and (T2 - T1) is the temperature difference across the substance. For convective heat transfer, the relevant equations are Q = mc∆T, and if a phase change is involved, Q = mLf or Q = mLy. Therefore, the correct option corresponding to the equation mentioned in the student's question is option (a): Convection in the fluid = Conduction in the solid.
