Sunrise is the moment when the upper edge of the rising sun appears to be right at the horizon assuming an unobstructed view. That includes the effect of refraction of the sunlight by the atmosphere, which averages about 34 arcminutes. Atmospheric conditions in the sunlight's path to the observer can cause sunrise times to vary by over a minute due to the amount of refraction. At higher latitudes the variation can be many minutes due to the smaller angle between the horizon and the sun's apparent path. For the purpose of calculations, scientists define sunrise to be when the center of the sun is 90.83333° below the observer's zenith. The extra 0.83333°, or 50 arcminutes, accounts for the 34-arcminute average refraction and the 16-arcminute apparent radius of the sun.
objects dropped exactly at the same moment will hit the ground (on earth) at exactly the same moment.
It depends on exactly where in Kansas you are refering to.
sunrise and sunset if i am right
Solar sunrise refers to the moment when the first part of the sun becomes visible above the horizon at sunrise. This event marks the beginning of a new day, and the time of solar sunrise varies depending on the observer's location and the time of year.
At the moment, sunrise in Yorkshire is 8.20am, but this obviously changes through out the year!
Sunrise is the moment that the leading edge (sometimes called limb) of the sun first breaks above the horizon. Sunset is the moment that the trailing edge (the last of the sun as we observe it) disappears below the horizon.
The moment of sunrise depends not only on the date, but also on your exact geographical location.
Yes, sunrise is defined as the moment when the upper limb of the sun first appears above the horizon in the morning. This marks the beginning of daylight.
For two antipodal locations (on opposite sides of the Earth) it will be sunrise for one when it is sunset for the other.Also, on the winter solstice, areas very near the North Pole or South Pole may experience a "day" of only a few minutes length, with sunrise quickly becoming sunset and the Sun never leaving the horizon. At the Poles themselves, the period from sunrise to sunset, and sunset to sunrise, is 6 full months.
All over the world, the Sun rises more or less in the east. That is, not always exactly in the east, but the point of sunrise is always closer to the east than to the west.
That is the time the armistis was signed in WW1
it was made to capture a moment in time quickly and exactly.
