Balsa wood has a thermal conductivity of 0.048 W/(m*K). What is the thermal flux for a sheet of balsa wood that is 2 cm thick if the temperature
on one side of the sheet is 10 degrees C and on the other side it is 43
degrees C?*

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b. b. at twice the distance, the magnitude of the field is 2b. c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
