I need help on these problems please!!!!!!! Everything !!
Questions 1. Calculate the force on an electron if the accelerating plates are held at a potential difference of 600 V. (Note this is V,) Assume a distance of 1 em between the plates. Compare this force, F, to the force due to gravity, F,; i.e., calculate Can we safely neglect the effect of gravity in this experiment? 2. For the case above, what is the speed of the electron, va, in terms of the speed of light? If v, >0.5c (roughly), then Newtons laws begin to break down, and we must use relativistic equations which obey Einsteins theory of relativity. Are relativistic equations necessary in this case? 3. If the electron above passes directly between the pair of parallel plates used in this experiment, what voltage must we apply to the plates to send the electron crashing into one of the plates? (Note, this is Va.) The electron is initially moving parallel to the plates equidistant from either plate. 4. How long is the electron under the influence of the electric field due to the plates? This is known as the interaction time, tint it is often a quantity of interest.

    please I need help with the data sheet INTRODUCTION The chemical and physical properties of substances are influenced by the way in which valence electrons are distributed and by the three-dimensional shape of the molecule or ion. X- ray and neutron diffraction, infrared, Raman and microwave absorption spectroscopy, as well as dipole moment measurements are used to ascertain the three-dimensional structure of a substance. Thus, techniques are available which can identify the geometry of substances. Results of these measurements generally...

    Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
