Questions 171719-19\newlineA solid disk of mass M M and radius R R is freely rotating horizontally in a counterclockwise direction with angular speed ω \omega about a vertical axis through its center with negligible friction. The rotational inertia of the disk is MR2/2 M R^{2} / 2 . A second identical disk is at rest and suspended above the first disk with the centers of the two disks aligned, as shown in the figure above. There is no contact between the disks. The second disk is dropped onto the first disk, and after a short time they rotate counterclockwise with the same angular speed wy.\newline1717. Which of the following properties of the two-disk system must be conserved between the time the second disk is dropped on the first disk and the time that the two disks begin rotating with the same speed?\newline(A) Kinetic energy only\newline(B) Angular momentum only\newline(C) Both kinetic energy and angular momentum\newline(D) Neither kinetic energy nor angular momentum\newline(E) It cannot be determined without knowing the nature of the forces between the two disks.\newline1818. The interval of time Δt \Delta t is the elapsed time from the moment of first contact between the two disks until they are both spinning at the same angular velocity. Which of the following expressions gives the magnitude of the average torque that the first disk exerts on the second disk?\newline(A) MR2ωf M R^{2} \omega_{f} \newline(B) MR2ωfΔt \frac{M R^{2} \omega_{f}}{\Delta t} \newline(C) MR2ωf2Δt \frac{M R^{2} \omega_{f}}{2 \Delta t} \newline(D) 2MR2ωfΔt \frac{2 M R^{2} \omega_{f}}{\Delta t} \newline(E) It cannot be determined without knowing the nature of the forces between the two disks.\newline1919. The two disks are now shifted so that the axis of rotation goes through a point on the edge of the disks.

Attempts \square 33 Keep the Highest 3/8 3 / 8 \newline33. Venn Diagrams from the Boolean Standpoint\newlineWhen evaluating syllogisms for validity, enter the information from both premises of the syllogism into a Verin diagram. If the argument form contains only one universal premise, then enter that premiso first. Once you have completed the diagram representing both premises, determine whether the conclusion must necessarily be true as well, given the information from the premises; If the conclusion must be true, then the argument is valid, If the conclusion could still bo false, then the argument is invalid. When checking for validity, always begin from the Boolean standpoint. It is important to remember that the Boolean interpretation of categorical statements does not assume existential import (in other words, it does not assume that an unshaded region of a Venn diagram must have any existing members). This can be a key factor when interpreting a diagram to determine whether a syllogistic form is valid or invalid.\newlineUse the following Venn diagram tools to construct diagrams that represent the given syllogistic forms from the Boolean standpoint. Once you have constructed your diagrams, interpret them to determine whether each syllogistic form is valld or invalld from the Boolean standpoint. Indicate your answers using the dropdown menus below each diagram.\newlineTool tip: Mouse over various regions of the Venn diagram to highlight those reglons. Click multiple times to rotate through the possible markings within that region. \qquad \newlineArgument 11\newlinePremise 11: All S S are E E .\newlinePremise 22: All Q Q are E E .\newlineConclusion: All Q \mathrm{Q} are S \mathrm{S} . \qquad
