Expert Solution & Answer
Check Mark
To determine

The explanation for the statement “The Milky Way was once thought to be murky or milky but it is now considered to be made up of point sources”.

Answer to Problem 1Q

The Milky Way was once thought to be murky or milky but it is now considered to be made up of point sources because earlier very large telescope were not available and the group of stars that appears to be cloudy.

Explanation of Solution

The sun and all the planets around and other stars around them are the part of galaxy known as Milky Way galaxy. The Milky Way was once thought to be murky or milky but is now considered to be made up of point sources because now very large telescope are available which gives the clear picture of galaxy.

Initially it was considered as murky because of the group of stars that appears to be cloudy but, now it is considered to be point sources because vary large telescope proved that these clouds are extravagate outside the galaxy.

Conclusion:

Therefore, the Milky Way was once thought to be murky or milky but it is now considered to be made up of point sources because earlier very large telescope were not available and the group of stars that appears to be cloudy.

Is  work function of a metals surface related to surface energy  and surface tension? What is the need to the work function component in the math of tension of metal surfaces that cannot be provided by existing equations of surface energy and surface tension? What are the key differences in each parameter and variables that allow for a differentiation of each function?  What has a more significant meaning work function, surface tension or surface energy? Are there real differences and meaning? Please clarify and if possible provide examples . Does surface tension dependant on thickness of a metal or type of metal surface all having the same thickness? Clearly temperature has a profound change on surface tension what other variables besides temperature are key to surface tension.  What if any is there a connection between crystal structure of the element and surface energy and tension? This is NOT a Assignment Question!!!
