The free-body diagram below shows the forces acting on a bicycle as the
rider pedals to the right. the vectors are not drawn to scale. the bicycle has a
weight of 700 n and a pedaling force of 325 n. as it moves, it encounters 100
n of air resistance. what is the net force on the bicycle in the x-direction?

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

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions
