did you tried first if you did I can help
The rate of flow of electric CHARGE past any point is described in the unit of electric CURRENT ... the Ampere.
120/6=20 ohms :) would be the ans
Pressure at a given surface is given as ratio of normal force and area
so here force due to heel of the shoes is given as 80 N
and the area of the heel is given as 16 cm^2
so we can say

here we have
F = 80 N



so pressure at the surface due to its heel will be 5 * 10^4 N/m^2
