Explanation:
Hey, there!
The liquid pressure varies with depth because liquid pressure is directly proportional to the depth of liquid from the free surface of the liquid. so, more the depth more the pressure and less the depth less the pressure.

Answer:
Stretch is 0.816 m
Explanation:
Data :
Force = F = 10 N
Spring constant = k = 15 N/m
By using formula
F = - kx²
Where is displacement or stretch
x² = F/-k = 10/15 = 0.667
x ² = 0.667 ⇒ x=√o.667
x = 0.816 m
