In this last step, return to Step 10 in your Lab Guide to calculate the error between your calculated specific heat of each metal and the known values in Table C. Follow the directions given in your Lab Guide, using this formula: Error = 100 times StartFraction calculated c subscript metal minus known c subscript metal over known C subscript metal EndFraction.

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?
