Give two advantages of using nanoparticles in sun
creams.

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

Give an example in which the electrical energy changes to light energy

Based on this activity, is kinetic energy always transformed into potential energy?
