Is at the heart of the scientific process. it can assist with everything from determining a good scientific question to allowing others to examine and verify results

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

Red light strikes a metal surface and electrons are ejected. if violet light is now used with a 10% greater intensity, what will happen to the ejection rate (number of ejected electrons per second) and the maximum energy of the electrons? a) greater ejection rate; same maximum energyb) same ejection rate; greater maximum energyc) greater ejection rate; greater maximum energyd) same ejection rate; same maximum energye) none of the above answers are correct
