An optical disk drive in your computer can spin a disk up to 10,000 rpm (about 1045 rad/s ). If a particular disk is spun at 704.8 rad/s while it is being read, and then is allowed to come to rest over 0.301 seconds , what is the magnitude of the average angular acceleration of the disk

Natural forces that can alter ecosystems include seasons and climate changes. t or f

Ascientific blank must be testable and capable of being proven false?

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
