H4 Answer the following question regarding field of view measurements. Enter your answer as a whole number (decimal format). Imagine you are using a microscope where the diameter of the field of view at 4x is 10mm. You view the microbe below at 100x. What is the size of each individual microbe? DO NOT ADD UNITS. D1=4x and M1=5mm
Radiocarbon dating is the most common and important absolute dating technique in archaeology. The method has proven invaluable for providing calendar dates for a range of different materials and many different time periods. Radiocarbon dating, however, is not without its limitations and uncertainties, so it is important for archaeologists to be aware of a range of issues when using the technique. For the second part of this assignment, please answer the questions below.  6. List two kinds of archaeological materials can be dated using the radiocarbon method and two that cannot be dated with radiocarbon.  7. In one or two sentences, explain why radiocarbon ages need to be calibrated into calendrical ages?  8. A radiocarbon date on wood charcoal was obtained from Layer N in the stratigraphic profile above. The date has a radiocarbon age of 5500 BP ± 50 yrs and it calibrates to 4450-4260 cal. BC. Burial W in Layer E was also dated and has a radiocarbon age of 5000 BP ± 30, which…
Which of the following is least reasonable regarding the difficulty in contacting extraterrestrial life using space flight and radio communication. Group of answer choices Space flight to the nearest star would take thousands of years with current technology.   Even if another intelligent civilization is within a few hundred light-years of us, conversations would be very slow with a turnaround time of decades or even centuries.   The spacecraft that NASA sent to Proxima Centauri a few years ago should be approaching its target within a decade or two, depending on solar wind conditions.   Earth has been broadcasting at radio wavelengths since the 1930's, so any civilization within a radius of about 100 light-years or so could have received the broadcast by now.   Without some major breakthrough, interstellar space flight is totally impractical.
