Please fill out the template with the work for this problem. Note that you need to have a picture, list of knowns and unknowns, the general equation/s you will use, the math steps to solve for the unknown, only plug in the numbers after you have solved for the unknown, and the answer with units included.
A grandfather clock has a pendulum that consists of a thin brass disk of radius r and mass m that is attached to a long thin rod of negligible mass. The pendulum swings freely about an axis perpendicular to the rod and through the end of the rod opposite the disk, as shown in the figure below. If the pendulum is to have a period I for small oscillations, what must be the rod length L? (Use any variable or symbol stated above along with the following as necessary: g for the acceleration of gravity.) L = Rotation axis L

Please illustrate the problems. Only need the diagrams/ illustrations and not the answers In a given fluid, positive ions, each with three excess protons, move towards right at a steady rate of 4.5 x 1019 ions per minute and negative ions, each with two excess electron, move towards left at a steady rate of 2.5 x 1020 ions per minute. Determine the current directed to the right.An electric circuit has a battery with an EMF of 1.50 V. Its positive terminal is connected to its negative terminal by a copper wire in a circular loop having a radius of 0.500 m. Solve for the drift velocity in the wire if there is one free electron per copper atom.
