Which statement(s) is(are) true for photomultiplier tubes?I     Photomultiplier tubes are very sensitive detectors, amplifying the photoelectron current by approximately 1 million.II     Emitted photoelectrons are accelerated toward positively charged electrodes called dynodes.III     Electrons strike the dynode with a kinetic energy less than the original emitted kinetic energy.IV     For each electron striking a dynode, more than one electron is knocked free. The additional electrons are accelerated toward the next dynode in the detector where amplification is repeated. Select one: a. II, III, and IV b. II c. I, II, and IV d. II and III e. I and IV

This is not a project and/or assignment for marks, as theses are textbook questions, and will not be copying the tutors work/answers. Please answer all the questions in the space provided and in full details. Answer in complete sentences. Take as much time as needed to answer all of the questions correct please and thank you. Will write a very neat and wonderful review afterwards.

please help me with both questions

Graph: Take a graph sheet and divide it into 4 equal parts. Mark origin at the center of the graph sheet. Now mark +ve X-axis as Vf, -ve X-axis as Vr, +ve Y-axis as Ifand –ve Y-axis as Ir. Mark the readings tabulated for Si forward biased condition in first Quadrant and Si reverse biased condition in third Quadrant.

question: Suppose that you want to sort blocks of different heights automatically. How can this task be done with IR Sensors

You can use the pressure meter tool to keep track of the pressure at a particular place over time. Place the detectors Into the middle of your sound wave box. Hit play and then PAUSE and adjust the position of your pressure sensors. 7. Where particles are close together (In the light color bands). pressure is 8. Where particles are further apart (In the dark color bands), pressure is Hopefully you noticed that a high pressure reading matches a where the particles are close together in a light-coloured band. This is called an area of wave compresslon. Where particles are further apart in the dark coloured band, there Is less pressure. Scientists call these areas of the wave rarefactlons. • Set the amplitude to zero. This shows where the particles would be if there Is no sound. • Slowly Increase and decrease the amplitude. • Use the pressure tool to measure pressure. You may have to do this a few times to see a pattern. 9. Insert a screen capture of pressure waves that would Indicate a…

Q8 - You wish to end up with a 2um width metal line (measured at the top of the metal lead cross section). A) You are using an isotropic wet etch process on a 1um thick metal layer. What linewidth should the protective photoresist line be to get these results? Sketch the resulting structure before photoresist strip. B) now you are using a completely anisotropic etch, what is the requisite linewidth of the photoresist to achieve the same end goal? Sketch the resulting structure before the stripping of the photoresist.
