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.
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 …
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
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
16 thg 8, 2025 · Spring tides occur during syzygy of the Earth, Sun and Moon. During a new moon, when the sun and moon are both pulling harder on the near side of the earth than the far side, this makes perfect sen...

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.
15 thg 2, 2017 · I’ve heard from the likes of Brian Cox that what we see of the sun during a sunset and sun rise is actually the mirage of the sun. The Sun has actually set/risen and we see it due to the way light is
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...
