FOR HIGH SCHOOL PHYSICAL SCIENCE Using what you know about the periodic table, list some patterns that organize the elements in terms of atomic number, atomic mass and valence electrons? What do the periods (horizontal rows) and groups (vertical columns) of the periodic table indicate to us about the elements that are categorized within them?

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?

Avehicle has an oil leak that is causing the entire oil pan to be wet, but inspection reveals no exact source after cleaning off the oil residue. technician a says to install a fluorescent dye in the crankcase and operate the engine, then re-inspect for leaks with a special light (black light). technician b says the oil leak may be coming from a source at the top of the engine, such as a valve cover gasket. who is correct?
