Let’s talk about your opinion on sci-hub
Which of the following statements is appropriate? a. “Waves” used for morphological observation include waves other than electromagnetic waves (e.g., material waves). (b) Observations using electromagnetic waves with wavelengths shorter than that of visible light are not used in astronomy and earth science observations. c. Due to the phenomenon of diffraction, there is a negative correlation between the wavelength of the wave and its observable magnitude. Question 11 Choose one: c a, a, b b, c c. Which of the following statements is appropriate? (a) Observation of visible light from an aircraft cannot provide information on topographic elevation, so the use of GPS is indispensable. (b) Because remote sensing observation covers a wide area, sunlight, which is a naturally occurring “wave,” is indispensable. c. Using the phase information of waves, it is possible to observe changes of a few centimeters in topography. of the topography can be observed by using the phase information of waves. Question 21 Choose one: a A, A, B B, C C Which of the following statements is appropriate? (a) Electron microscopy is a type of virtual microscopy that uses data stored on a computer. (b) When a material is irradiated with electron beams, various “waves” are generated by the interaction with the material. (c) Observation by reflection electrons shows that magnetite (Fe3+) is more stable than quartz (SiO2 ) appears brighter than magnetite (Fe3O4 ) appears brighter than quartz (SiO2). Question 31 Choose one: b a, b A, C B B, C

Sci-Hub is really valuable to me and my stuedents.
Let’s talk about your opinion on sci-hub
1. For me is really good, because it can help many people around the world for research their studies 2. Of course, it really helps me 3. I think you can add feature like search the title of the book or journal so i / they dont have to post for same title 4. For me i will cry very much :( 5. I dont have any question, BTW i really love this webiste so much, but in my country sadly they don't know that this website (wosonhj.com) exist
