Investigators are exploring ways to treat milk for longer shelf life by using pulsed electric fields to destroy bacterial contamination. one system uses 8.0cm diameter circular plates separated by 0.95cm. the space between the plates is filled with milk, which has the same dielectric constant as that of water. the plates are briefly charged to 30,000v. what is the capacitance of the system? how much charge is on each plate when they are fully charged?

Bone-strengthening physical activity done increases bone-mineral content and bone density in youth.

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?

A2-kg bowling ball is 2.5 meters off the ground on a post when it falls. just before it reaches the ground, it is traveling 7 m/s. assuming that there is no air resistance, which statement is true?
