(b) Estimate the rate at which ice would melt in a cubical wooden box of length 50cm and thickness 2.5cm. Assume that the external temperature is 40°C. Given thermal conductivity of wood is 0.17 Wm¹ K-¹ and latent heat of fusion of ice is 336 x10³ J/kg.​

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?
