(a) A 135 g mass of aluminum is formed into a right circular cylinder, shaped so that its height equals 2.5 times its diameterCalculate the resistance between the top and bottom faces of the cylinder at 20°C(b) Calculate the resistance between opposite faces if the same mass of aluminum is formed into a cube.
didn't I do this a while back? I'll give you the highlights Resistance of a wire in Ω R ρL/A ρ is resistivity of the material L is length in meters A is cross-sectional area in m? A πr? density Aluminum 2700 kg/m? resistivity Al 28.2 (nΩ-m) Use the density and mass to get volume you have 3 equations in 3 unknowns1) R ρL/A 2) V AL 3) L 2.5d where d 2r and r √(A/π) .
Best to use foil, because otherwise the juice of the apple will transfer its moisture and the stuff won't stay lit
yes, unless you want ashes down your throat
