The same thin hfo2 sample from question 1 was analyzed on an auger spectrometer and the hf nvv electron was measured to have a kinetic energy of 184 ev using a 10 kev primary beam. at what kinetic energy would the same electron (hf nvv) be observed if the primary beam energy was increased to 25 kev? from the kinetic energy, what can we infer about the sample?

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold
