Why do astronomers use a different form of measurement than we are accustomed to using?
Because the distances are so incredibly far that to express them in miles or (god forbid) feet, inches etc would be incomprehensible. It would just be a wall of numbers. The closest star to our solar system is about 4 and a half light-years. Or roughly 50 trillion miles. To travel on earth as far as it is to get to the nearest star (out of about 300 billion stars in our galaxy alone) you would have to go around the world roughly 2 billion times. So rather than saying a galaxy is 9,394,000,000,000,000,000,000 miles away, they say it's X number of astronomical units, or X amount of lightyears away.
What are the test instruments used in electronics?
Some test instruments used in electronics are:Multimeter - Used to measure voltage, ampere and resistanceOscilloscope - Used to measure frequency and oscillations
What is the name of the muse song used for 28 Weeks Later?
Shrinking Universe
Is donnie darko a hero or crazy?
In the tangent universe he had increased strength, ability to manipulate water/fire, and telekinesis. He used these powers to save the universe. He is not just a hero, but a superhero.
What is used to measure a perimeter?
to measure the perimeter we need a figure with boundaries and all the sides with dimensions
Why light years are used to measure distances in the universe?
because it is the fastest way to measure in very long distances for example earth to other far away planets
What do scientists use to measure distances in space?
They use lightyears and AU (Astronomical Units). They use kilometers, AU's and light years!! *Parsecs are also commonly used
The galactic distances used to measure the acceleration of the universe are determined by observations of what?
exploding white dwarfs
What units do scientist use to measure distances in space?
They use lightyears and AU (Astronomical Units). They use kilometers, AU's and light years!! *Parsecs are also commonly used
What two units are used to measure distance in space?
Lightyears and miles
What is the other units of measurements being used in long distances?
furlongs, miles, kilometres, lightyears etc.
What type of measurement is used to measure the distance between the milky way galaxy and other galaxies?
lightyears
Inches are used to measure this?
Lengths or distances.
What unit is used to measure distances on land?
It depends on what you are trying to measure. Long distances usually are measured in miles. Survey distances usually are measured in feet.
Why did the Au is not used to measure distances on earth?
AU is not used to measure the distances on earth, because a astronomical unit is a unit of measurement equal to the distance between Earth and Sun. So that's why you cannot use Au for measure the distances on Earth.
When do you use meters to measure something?
Meters are used to measure distances.
Cepheid variable stars have been used to determine the?
1)placing cosmological constraints on the expansion of the Universe through the determination of distances to galaxies 2)to measure many characteristics of our galaxy and our relationship to it
