24. Consider the force field \[ \mathbf{F}(x, y)=\left(x y+2 y^{2}\right) \mathbf{i}+\left(3 x^{2}+y\right) \mathbf{j} . \] Find the work done by $ \mathbf{F} $ to move a particle from $ (0,0) $ to $ (1,1) $ along (a) $ y=x^{2} $ (b) the $ y $-axis to $ (0,1) $ and then along the line $ y=1 $ (c) path (b) and then returns to the origin along path (a).

Find a (steady state) temperature distribution in a partially submerged pipe shown. 0.5 -20° 3 6 +10° 5 water Temperature of air = -20°, fluid (inside) = + 15°. Temperature in soil: Changes from +2° at the bottom of the pipe to the air temperature at the surface, as a linear function of the radial angle. Pocket of water, at 0º as shown When using Fourier series in angular coordinate $\theta$, retain the number of terms that provides reasonable accuracy. Comment on: how this number changes with the radial coordinate. Plot lines of equal temperature. Sketch zones where temperature gradients are highest (in these zones, mechanical stresses, caused by temperature gradients, will be the highest)
