A long homogeneous resistance wire of radius ro = 5 mm is being used to heat the air in a room by the passage of electric curren
t. Heat is generated in the wire uniformly at a rate of g=5'107 W/m as a result of resistance heating. If the temperature of the outer surface of the wire remains at 180°C, determine the temperature at r = 2 mm after steady operation conditions are reached. Take the thermal conductivity of the wire to be k = 8 W/m x °C.
Explanation: There is no fundamental difference between nano-composite and conventional composites. Conventional composite have a particular structure similar like the nano- composite material which have a composition of the nano-crystals.They both have a hardness to some extent and also face damage under extensive load impact. Thus , they have certain difference but that can't be considered as the primary or fundamental.
Answer: Yes army people are good people but it also depends on how you fraze that some have been in trouble before but it doesnt mean there bad people we all make mistakes
