Question 27 2 pts The following information is relevant to the next 3 (THREE) questions. Incident beam (x rays or electrons) Target Caluminum crystals) (a) (b) (c) A beam of electrons with kinetic-energy 35 kev is directed onto a thin powder metal target as shown, and the image of the scattered electrons is recorded on a photographic plate. When a beam of x-rays was used instead of the electrons, the general features of the image produced is identical to that of the electrons. Part 1 What is the momentum of the electrons used in the electron measurement? (Units: zg.ms 1 = 10-24 kg.ms*1)Question 28 2 pts Part 2 What is the wavelength of these electrons? (Units: pm) Question 29 2 pts Part 3 What is the energy of the x-rays that were used? (Units: kev)Question 30 2 pts The following information is relevant to the next 2 (TWO) questions: The wreck of the Titanic lies at a depth of about 3,800 metres. A remote controlled submersible vehicle is attempting to reach and film the wreck. Data: Density Sea water = 1.024 x 103 kg/m3 Part 9 What was the absolute pressure in atmospheres (atm) at this depth? Question 31 2 pts Part 2 What is the external force due to pressure on a window of area 24 cm?? (Units: Newtons)
