Why is it important to measure accurately?
it is important to measure mass accuratley because if you dont everything is going to fail.
Why would astronomers measure the parallax angle of a planet or star?
It's distance
How do you accurately measure volume of a liquid?
Use a volumetric flask.
What is the fastest lion speed ever recorded?
It's difficult to accurately measure the speed of the worlds fastest lion, because there is no way to measure the speed of every lion in the wild. Most sources say 50mph so using logic, no lion has run more than 55mph tops...
Why is it difficult to measure the Hubble constant H?
Both the speed and the distance of distant galaxies must be measured accurately.

What is used when astronomers measure the distance from the sun to the earth?
Parallax is the method that astronomers use to measure the distance from the sun to the earth.
Who is the greatest genious ever lived?
That's difficult to say. IQ measurement is a relatively recent development. That and the fact that the higher levels of IQ are extremely difficult to measure accurately.
Will astronomers measure all the distances of the 100 billion galaxies in the universe?

What decimal position can you measure accurately using a thermometer?

Do astronomers measure the distancein the solar system in kilometers?
no the measure it in AU'S =ASTRONOMICAL UNITS
Do the gravitational constant change with time or place?
That's a really hot question among cosmologists and astronomers. No positive evidence of a change through time has been found, but then, how would you look for it or measure it out in the universe ? ! ?
How do astronomers measure the distance to nearby stars?
Astronomers use a method called parallax to measure the distance to nearby stars. Astronomers can measure parallax by measuring the position of a nearby star with respect to the distant stars behind it. Then, they measure the same stars again six months later when the Earth is on the opposite side of its orbit.
How do astronomers measure distance to the stars?
With a long measuring tape.
