I can help, what’s the question?
Answer : The value of
is
.
Explanation :
As we are given 6 right angled triangle in the given figure.
First we have to calculate the value of
.
Using Pythagoras theorem in triangle 1 :




Now we have to calculate the value of
.
Using Pythagoras theorem in triangle 2 :





Now we have to calculate the value of
.
Using Pythagoras theorem in triangle 3 :





Now we have to calculate the value of
.
Using Pythagoras theorem in triangle 4 :





Now we have to calculate the value of
.
Using Pythagoras theorem in triangle 5 :





Now we have to calculate the value of
.
Using Pythagoras theorem in triangle 6 :





Therefore, the value of
is
.
Answer:
Abrasion and Attrition both mean the wearing down of an object, however,
Explanation:
Atrition refers to the breaking off of particles (erosion) which occurs as a result of objects hitting against each other. Abrasion leads to surface-level destruction over time, whereas attrition results in more change at a faster rate.

Answer:
Water
Explanation:
Acetone has a higher vapour pressure than water because acetone molecules only experience dispersion forces and diploe interactions as the dominant intermolecular forces.
In addition to these mentioned, water molecules are held together by strong hydrogen bonds. Therefore, water has a much lower vapour pressure than acetone and requires greater energy to break these hydrogen bonds and convert the liquid water to gaseous state.
