How much faster does a 10-micrometer aerodynamic diameter particle settle than a 5- micrometer diameter particle of the same shape and density? (use stokes law)

When you drop a pebble from height a it reaches the ground with speed v if there is no air resistance. from what height should you drop it so it will reach the ground with three times the speed? (a) 9m (b) 3m (c) 6m (d) 18m

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

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
