Answer:

Explanation:
Given that
P = 4 KPa
Contact angle = 6°
Surface tension = 1 N/m
Lets assume that atmospheric pressure = 100 KPa
Lets take that density of water =
So the capillarity rise h


h= 9.61 m
We know that for capillarity rise h





Answer:
than look inside it
Explanation:
well if you need to inspect something, looking is very important
