- Three particles with charges q₁ = +10 μC, q₂ = -20 μC and q3 = +30 μC, are positioned at the vertices of an isosceles triangle with sides a = 0.1 m b = 0.06 m as shown in the Figure. How much work must we do to exchange the positions of q₁ and q3 ? Give your answer in Joules. Hint: What is the Energy of the system of 3 charges as they are and what is its Energy when the positions of 91 and 93 are exchanged? What does the difference between these energies represent?- 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?can this be rewritten in a legible way so i can understand how you got 335m
