Units such as light years and astronomical units are useful because they can be used to measure very large distances without yielding extremely large numbers.
red and blue light is most useful. But others are not.
Galaxies are always calculated in light years or parsecs. Most galaxies are calculated in mly of kpc (Million light years or thousand parsecs) because of the distances.The Andromeda Galaxy is our closest large galaxy, and that is 2.54 mly or 778 kpc.If we used AU that would equate to 160,000,000,000 or 160 billion AU.
A thermometer and light meter are the most useful when measuring two environmental changes.
well we use three main ones : Light years, parsecs and kilometers, but we usually only use kilometers for our inner solar system __________________ There is also the Astronomical Unit, AU, which is the average distance between the earth and the sun. A parsec is roughly 3.3 light years, and a light year is the distance covered by light in a vacuum in one earth year. um also the distance requires the sun. Since astronomers did not know where to start, they measured everything in the universe starting with the sun.
micrometer
because there is more sun light
A thermometer and light meter are the most useful when measuring two environmental changes.
Red light and blue light.Photosynthesis is not efficient under green light.
Probably AUs or Astronomical Units. 1AU= 93 million miles or about 150 million km. 1AU is the distance from the Earth to the Sun.
The most useful scale for measuring distance depends on the specific context. For very short distances, scales like centimeters or inches are commonly used. For longer distances, scales like meters, kilometers, or miles are more practical. In astronomy or geology, scales like light-years or astronomical units may be used for extreme distances.
There are many tools used in measuring meteorological changes. The most useful tool depends on which factors are measured. A light meter or photometer measures light intensity while a barometer measures atmospheric pressure.
No, it is too large a unit so that most of the numbers in the model would be extremely small. The earth is only 0.000015 light years away from the sun. Even Neptune, the furthest planet is just 0.0005 light years.
