Review the גמרא דף ה. “היה פחות מעשרה טפחים until “אמר אביי”
Questions:
Why does רב יוסף say when the קורה is higher than 20 Amos you only need a build up of ground of a tefach underneath, but if the קורה is below 10 tefachim one needs to excavate an amount of four tefachim inside the mavui?
See “רש”י “רב יוסף
According to Rashi is the קורה acting as a מחיצה?

Is the case of the gemara that the קורה is placed within 10 tefachim of the ground or the walls of the entire מבוי are less than 10 tefachim?

Focus on the second – fourth explanation

Explanation #2
According to which reason does the requirement to have 4 tefachim line up with – קורה משום היכר or קורה משום מחיצה?
Learn Rashi very carefully.

Questions:
Why does Rashi assume that the outer face of the קורה descends according to the opinion of קורה משום מחיצה?
Why is a build up of a tefach underneath the קורה insufficient? Once the height is reduced between the קורה and the ground the Mechitzah should descend and service the entire mavui?

Learn second half of תוס’ דף ד:-ה “מותר starting from “ואין להקשות”
Tosfos asks a major question:
According to the second explanation everyone agrees it is מותר להשתמש תחת הקורה and a build up of four tefachim is required because קורה משום מחיצה. This contradicts the premise of the first explanation of the Gemara (according to Tosfos) that everyone agrees קורה משום מחיצה and if its מותר להשתמש תחת הקורה only a one tefach build up is required?
Learn תוספות רבינו פרץ who explains Tosfos answer.
See גאון יעקב ד: “לימא בהאי קמיפלגי who explains the point of argument between the first and second explanation according to Tosfos. See the end of the paragraph and how he gives a different explanation of the position of Rashi in the first explanation of the Gemara and how he addresses the following questions we asked yesterday
According to the first explanation does Abaye and Rav Yosef hold קורה משום היכר or קורה משום מחיצה?
Rashi (רש”י דף ד: “מותר) discusses the need to see the קורה so why does Rashi need to add that we view the edge of the קורה as descending and creating a closure. It seems that Rashi is requiring both the element of היכר and מחיצה?

Conclusion of Sugya: חציצה
The Rambam (רמב”ם ה’ מקוואות פרק ב’ הלכה ט”ו) brings a machlokes in regards to Hilchos Chatzitzah of how we evaluate the majority of the hair independent of the body
The גאונים – a chatzitzah on majority of the hair will invalidate the Tevilah
The רמב”ם – calculate the majority of the hair and body collectively
https://hebrewbooks.org/pdfpager.aspx?req=58964&st=&pgnum=214

The ח’ הגרי”ז on this רמב”ם explains the torah views the body and the hair as two separate entities
The גאונים – Drasha that chatzitzah applies to hair requires the hair to be immersed in the water without a chatzitzah but it still remains an independent entity than the body
The רמב”ם – Drasha teaches in regards to chatzitzah we view the hair and the body as one unit.

Major Question:
According to the גאונים if the hair is considered an independent entity from the body what is the connection between one strand of hair to the next that we should evaluate all the hair as one unit?
