MIS NOTAS PREGUNTA A TU PROFESOR An eight-turn coil encloses an elliptical area having a major axis of 40.0 cm and a minor axis of 30.0 cm (see figure). The coil lies in the plane of the page and has a 6.15-A current flowing clockwise around it. If the coil is in a uniform magnetic field of 2.02 x 104 T directed toward the left of the page, what is the magnitude of the torque on the coil? Hint: The area of an ellipse is A = nab, where a and b are, respectively, the semimajor and semiminor axes of the ellipse. N.m 40.0 cm -30.0 cm-|

Help with h and I thanks

9. Please help answer this question, thank you so much! :)

- Figure above shows the cross section of a wall made of two layers. The thickness of the 2 nd layer is L2= 0.70L1. The thermal conductivities of the layers are 0.25 and 0.75 W/mK, respectively and thermal conduction is steady. If the temperatures at inlet and between the layers are Ti = 30.0°C and T=8 °C, respectively; what is the outside temperature To for unit area?
