How is the spin of an elementary particle measured?
Spin is either up or down and in positive half integer multiples of an angular momentum quantum constant: h/(2∏), where h is Planck's constant.
What is the synonym for the word tall starting with the letter H?
Hard is a synonym for tall when tall means difficult or not easy. For example, that is a hard (i.e., tall or difficult) order to follow.

''I'' comes after ''H'' in the alphabet.
What relationship is identified by Hubble's constant?
h=vd
Why is it difficult for astronomers to accurately measure a value for the Hubble constant H?
Astronomers find it challenging to accurately measure the Hubble constant (H) due to several factors, including the reliance on different methods that produce varying results. Discrepancies arise from measuring distances to galaxies using different techniques, such as Cepheid variable stars and Type Ia supernovae, which can yield inconsistent values. Additionally, the expansion of the universe is influenced by dark energy and cosmic structures, complicating the interpretation of data. These factors lead to uncertainties and debates over the precise value of H.
How would you work out the Hubble constant if the earth is 12.5 billion years old?
The Earth is not 12 billion years old. It is more like 5 billion years old. Hubble's constant cannot be determined from the age of the Earth. Hubble's constant describes how fast the universe is expanding. It can be determined by looking at the redshifts of stars that are a known distance away. From the redshift, one can determine the velocity of the star. Then Hubble's constant is defined as follows: v=Hd where v is the velocity of the star, H is Hubble's constant and d is the distance to the star. The current accepted value of Hubble's constant is about 71 km/s/Mpc.
If the hubble constant H is larger at great distances then what is happening?
An increasing Hubble constant at great distances indicates an accelerated expansion of the universe. This phenomenon is attributed to dark energy, a mysterious force causing the universe to expand at an increasing rate. It suggests that as the universe expands, the distance between galaxies grows larger, leading to a greater Hubble constant at greater distances.
How would a large value of H The Hubble constant affect the age of the universe What about small value of H?
A large value of the Hubble constant (H) implies that the universe is expanding rapidly, which would suggest a younger age for the universe because it would have taken less time for galaxies to move apart to their current distances. Conversely, a small value of H indicates a slower expansion rate, leading to an older universe since it would have taken more time for galaxies to reach their present separations. Thus, the Hubble constant directly influences our estimates of the universe's age, with larger values suggesting a younger universe and smaller values suggesting an older one.

Who stated that the universe is still expanding?
Hubble did not conclude that the Universe is expanding. Hubble thought the red shift indicated a unrecognized principle of nature. Hubble's constant actually shows the universe is bounded at R=150kMpc/31 and H= c/R = 62km/s/Mpc. The increase red shift velocity indicates a decreasing universe.
Space words that starts with a H?
Hubble telescope and hydrogen are space words. They begin with the letter h.
