A cyclindrical container filled with a liquid of density p rotates about an axis through its center with an angular velocity w. A Cartesian coordinate system in standard orientation is introduced with its origin at the lowest point on the fluid surface. The pressure above the liquid surface is P_0.
(a) Notice that a thin imaginary tube with cross-section area A lies along the -axis. Draw a free boy diagram for a slice of liquid within this tube, lying between generic coordinates x and x+dx. Seperately list the x-components of all relevant force vectors and the accel vector
(b) Substitute your results from (a) into Newton's second law. Derive a differential equation for pressure along the x-axis
(c) Integrate your result from (b) to obtain P(x) along the x-axis
(d) Derive a function y(x) which gives the shape of the liquid surface
(e) A cork (density pc < p) is attatche to the bottom of the container by a light string, at some nonzero distance from the center. Does the string bend in towars the center of the container or outward towards the walls? Explain.

help pls!!!!! Consider a tank filled with a liquid of constant density ρ up to an initial height ho in Earth. If the tank is moving with a constant linear acceleration ao, it is known from Fluidstatics that the isobars (lines with constant pressure) and therefore the free surface become a straight Line whose slope is a linear function of ao. If a0-0 then the surface becomes flat. On the other hand, if the tank is subject to rigid body...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
