27 thg 8, 2015 · For a while I thought that the reason I felt warmth from the sun was because my skin was being hit by photons, but then I realized that photons also hit me when I take an X-ray, but I don't feel an...
15 thg 2, 2011 · Do you want to know both how the Earth-sun distance is measured and how the speed of light is measured? Those are completely different things. As I asked before, separate threads, please.
20 thg 3, 2019 · Approximating the sun as a black body effectively means that it's surface temperature is 5800K. And, indeed, if we look at the most dominant wavelength of the sun spectrum, the maximal intensity comes from green wavelength which corresponds to a black body emitting radiation at a temperature of 5800K.
What is the isotope composition of hydrogen atoms in the sun? Are the ratios of protium:deuterium:tritium similar to those we find on earth? What does the nuclear fusion of hydrogen atoms in the sun
The Sun's energy comes primarily from fusion of light elements in its core. It is estimated that a very small fraction of mass of the Sun (~$10^{-12}$ times the abundance of hydrogen) is uranium (b...
I want to know how much lux the sun emits on a bright day - I don't mean when one stares directly at the sun, but rather when one walks casually outside when the sun is shinning brightly. Now the
15 thg 2, 2017 · If this is the case, then when we read things like what time sun sets and rises on websites, books, calendars, other official times, et al… does that mean when we see for example ‘sun set at 18:35’ is the time denoting the actual sun set taking into account of …

22 thg 4, 2022 · 0 I want to create an Augmented Reality (AR) application to show the sun's position where I need the 3D (XYZ) coordinates to plot in Augmented Reality (AR). Main question: I need to calculate the 3D coordinates (XYZ) from the sun Azimuth and altitude/elevation Look at the image.
These two distances help identify the location of the sun on the major axis of Earth's elliptical orbit. Assume that the major axis of Earth is on the x-axis. a. Find an equation of the Earth's orbit about the sun. b. With the given information, estimate Earth's speed around the sun in milers per hour.
