Module 1 Lab 1 Properties of Waves

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

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…

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 answer me fast fast  A platinum resistance temperature detector (RTD) is used to measured temperature of the hot gas. The resistance of sensing element is 250.3 ohm when it contact with hot gas. calculate the temperature of the gas. The RTD has a resistance of 120 ohm and 80 ohm at 100°C respectively. The temperature coefficient of platinum is 0.0039 C^-1.

Answer question clearly and fully. Make sure I can properly read out the steps. Include any and all equations used during the solving process.

3. State the number of significant figures in each of the following: (a) 542, (b) 0.65, (c) 27.25, (d) 0.00005, (e) 40 × 10°, (f) 20,000.

Deflection of an electron beam by electric fieldFollow the method to calculate how the voltage between the vertical plates varies the height of the election beam in the region between the plates.Method: 1- your Crooked tube is similar to the CRT of an oscilloscope. The main difference being that your tube has no horizontal deflectors, only vertical ones. The electron gun (“C”) is used to accelerate electrons. Draw a diagram of the barrel and deflector plates. Represent an electron coming out of the barrel with a horizontal velocity v0. 2- Assuming no deviation, trace the trajectory of the election between the plates. The undeflected position of the electron beam will serve as a reference. Suppose now that the electron, while crossing the plates, is deflected upwards. The vertical difference between the two points of impact on the TRC screen is the delta y deviation that we are looking for. If the electron is deflected upward, what is the orientation of the electric field between the…
