What is the speed of a wave which has a frequency of 200hz and a wave length of 0.50m

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

What is the most useful equation for electric power?

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
