1. Shoe sole We consider a shoe sole as a parallelepiped with height 1 cm, width 10 cm and length 30 cm. The sole is made of a material with electric resistivity $\rho \approx 10^{10} \Omega m$. a) Determine the electric resistance of the shoe sole. b) You are standing upright on two soles. What is your electric resistance? Our body is a good electric conductor, and its resistance is essentially determined by the soles of your shoes. c) Standing upright on two soles, you touch the dome of a Van der Graaf generator (metallic shell with radius $r \approx 30$ cm) with an electric potential of 400.000 V. How much time does the generator take to discharge itself through your body?
