figure 2 a shows a composite bat comprising of two diferent metals A and B of equal length 3 cm and diameter 15.0cm. if the thermal Conductivity (KA) of metal A is greater than that of a matal.
a.)Sketch Graphs to show how temperature varies along the composite bar from ∅1 to ∅2 under Circumstances where
1.)the bar is lagged
2.) the bar is unlagged
3.)given that KA=3.85A×10² W/m-¹k^-1 and K₂= 2.10 x 10²w/m/ k
