Explanation:
1.
Coming to your question, the colour of milk is White. It is white due to nature's light spectrum. It results in all the wavelengths of visible light being reflected into the eye. Casein and certain fats reflect wide ranges of wavelengths, causing milk to appear white in colour.

.Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Closer to the horizon, the sky fades to a lighter blue or white.
3.
Sunrise (or sunup) is the moment when the upper limb of the Sun appears on the horizon in the morning.[1] The term can also refer to the entire process of the solar disk crossing the horizon and its accompanying atmospheric effects

Well, before I give a direct answer, let us first know what is a day. It is the time taken by a celestial body to complete one rotation around its axis. Similarly a year is the time taken by a celestial body to complete one revolution around its host star or planet. A year is big and a day is small. Isn't it? No! A day on moon is equal to its year, and a day on Venus is larger than its year! Now the question arises, how many hours in an earth day? As it is known 24 hours. Right? Not. It's just an approximate and more convenient way of calculation of time. A closer answer is 23 hours, 56 minutes and 4.0916 seconds. The exact answer is irrational, and cannot be represented by common methods.
Hope the answer was helpful.
