Suppose the disk in the example has a hole cut out of it from its center, forming an annulus. The inner radius is r = 6.0 cm, and the outer radius is R = 15.0 cm. What is the potential (in V) of the disk at point P a distance of x = 23.0 cm from the center of the disk along the x-axis? The uniform surface charge density of the disk is 30 nC/m2.

I'd go for the one that says that knees are fulcrums, lower legs are levers and the ankles hold loads.hope it ,happy homework/ study/ exam!

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached
