A carbon nanotube is suspended across a trench of width s = 5 m that separates two

Question:

A carbon nanotube is suspended across a trench of width s = 5 μm that separates two islands, each at T∞ = 300 K. A focused laser beam irradiates the nanotube at a distance ξ from the left island, delivering q = 10 μW of energy to the nanotube. The nanotube temperature is measured at the midpoint of the trench using a point probe. The measured nanotube temperature is T= 324.5 K for ξ = 1.5 μm and T2  = 326.4 K for ξ = 3.5 μm.

Determine the two contact resistances, Rt,c,L and Rt,c,R at the left and right ends of the nanotube, respectively. The experiment is performed in a vacuum with Tsur = 300 K. The nanotube thermal conductivity and diameter are kcn = 3100 W/m · K and D = 14 nm, respectively.
