Daylight starts and ends with the centre of the Sun theoretically at a zenith distance of 90 degrees 50 minutes. It is more than 90 degrees to allow for atmospheric refraction and also because the top edge of the visible Sun must be level with the horizon.
The length of daylight depends on the Sun's declination and the observer's latitude. When these two factors are equal the Sun passes overhead at midday.
What else can I help you with?
The length of daylight on the moon is about?
The length of daylight on the moon is about two weeks, followed by an equal period of darkness due to the moon's rotation synchronizing with its orbit around the Earth.
What is the length of daylight on the Moon?
The length of daylight on the Moon is about 14 Earth days, followed by 14 days of darkness. This is because the Moon takes about 27.3 Earth days to complete one rotation on its axis, which also coincides with the time it takes to orbit Earth.
What are two factors that determine the brightness of a star?
distance from the sun and the age of the star
What two factors determine how bright a star looks from earth?
The two factors that determine how bright a star looks from Earth are its intrinsic luminosity (actual brightness) and its distance from Earth. Stars that are more luminous and closer to Earth will appear brighter in the night sky.
What two major factors determine the size of a star?
The two major factors that determine the size of a star are its mass and its age. A star's mass dictates how much material there is to form the star, while its age influences the stage of its life cycle, which in turn affects its size.
What is the length of the daylight on the moon?
Two weeks
The length of daylight on the moon is about?
The length of daylight on the moon is about two weeks, followed by an equal period of darkness due to the moon's rotation synchronizing with its orbit around the Earth.
What factors determine a biome?
Two factors that determine a biome are precipitation and temperature.
What are the two factors that determine the density of materials?
The two factors that determine a material's density (such as that of wood) are its mass and volume.
What are the three factors that determine height length and period of a wave?
The three factors that determine the height, length, and period of a wave are the wavelength, amplitude, and frequency. Wavelength is the distance between two corresponding points on a wave, amplitude is the maximum displacement of a wave from its rest position, and frequency is the number of oscillations per unit time.
What two factors are used to determine the size of a lathe?
The two factors that determine the size of a lathe are the "swing" and "distance between centers". The swing of a lathe is the length measured from the center of the hollow spindle or chuck to the nearest part of the bed multiplied by two. Distance between centers is the distance measured between the chuck and tail stock.
What are factors that determine the state of matter?
Temperature and Pressure are the two main factors that determine the state of matter.
What two factors determine the type of image formed by lens?
The focal length of the lens and the distance between the lens and the object.
What two factors determine the risk level in the Risk Assessment Matrix?
Probability and Severity are the two factors determine the risk level in the Risk Assessment Matrix.
What two factors determine the strength of friction between the two objects?
Two factors that determine the strength of friction between two objects is the smoothness of the surfaces in contact, and the weight of the object moving horizontally.
How do you determine width if the length and perimeter is given?
Subtract two times the length from the perimeter and cut that answer in half.
How do you find the length of two polygons if their perimeters are the same?
You cannot. Information about the perimeter is not sufficient to determine the length.
