Dec 26, 2014 · The same applies to the beams of light above them. The Sun is very far away and the beams are pretty much parallel, but they're pointing towards you, and perspective makes them appear to converge towards the vanishing point - which in this case is the Sun's location in the sky. The technical term for these beams is "crepuscular rays."
Feb 15, 2011 · Another way of calculating the earth - sun distance is to look at the centrifugal and the gravitational force. This solution assumes that one already knows the mass of the sun, but thats a different problem ;-).
May 31, 2015 · Stefan-Boltzmann: J = σT4 J = σ T 4. To lose 1 kW over 1 m 2 requires a temperature of. T = 1000 5.67 ⋅10−8− −−−−−−−−√4 ≈ 364 K T = 1000 5.67 ⋅ 10 − 8 4 ≈ 364 K. This assumes only the surface facing the sun loses heat by radiation: in other words this is only valid for a black surface mounted on a good insulator.
Feb 15, 2017 · The Sun has actually set/risen and we see it due to the way light is bent across the atmosphere. Apparently due to coincidence of the size and distance of the sun, its exactly the same size - so if we see 50% of the sun, the sun is 50% below the horizon. So, I understand all this, so here is my question :
A nonrotating Sun would also beget the observed anomalous precession, whose non-Newtonian component almost wholly arises from the inverse cubic term in the effective potential coming from the solution of the Einstein Field Equations for the Schwarzschild Metric. This metric assumes the central body (Sun in this case) is stationary and nonrotating.
When liquid water meets dry air, it is not in equilibrium; water molecules evaporate off the surface until the amount of water in the air creates enough vapour pressure to achieve equilibrium. When water is heated to a temperature of 100C, the vapour pressure equals that of sea-level air pressure. Since the air pressure can no longer overcome ...
The sun's temperature at the surface is ~5778 Kelvin which is much higher than the boiling point of Fe, Ni, or any alloy of the Fe-Ni. The atoms would disperse and would become lost in the sea of H and He nuclei, and wouldn't conceivably come anywhere near the core in one piece. Literally nothing about the sun would change in this scenario.
Nov 12, 2013 · Let us say that I am sitting in a room with all the drapes open. Bright sunlight is coming through the window. The whole room is brilliantly lighted. I will not be able to see the dust particles
Sep 22, 2015 · The Sun has neither of these (the centrifugal acceleration at the equator is only about 20 millionths of the surface gravity, and Jupiter is too small and too far away to have an effect) and simply relaxes to an almost spherically symmetric configuration. re rp = 1 + ϵ/3 1 − 2ϵ/3, ϵ = 5 4 Ω2a3 GM.
Jan 23, 2017 · 1. Light comes from luminous objects - it an energy emission. When it goes directly to our eyes we see the object. Some light reaches non-luminous objects, then bounces into our eyes; form this light we principally gain information about the non-luminous object, not the source. – JMLCarter.
