Answer:3764.282 KPa
Explanation:
Given gusher shoots oil at h=25 m
i.e. the velocity of jet is
v=\sqrt{2gh}[/tex]
v=22.147 m/s
Now the pressure loss in pipe is given by hagen poiseuille equation



For 25 m head in terms of Pressure

Total Pressure=
=3543.557+220.725=3764.282 KPa
Answer:
Option d is correct.
Explanation:
We know , resistance of a body is directly proportional to its length and inversely proportional to its area.
( Here,
is constant dependent on object material )
Writing
also :
( since they are of same material therefore,
is same.)
Now , if
.
Then 
Therefore, option d. is correct.
Hence, this is the required solution.
When you make a motion you change position over time.
Objects sink if they are denser than water
