CHAPTER 5: Relative equilibrium

Question 1

___________- of liquid is a condition where
the whole mass of liquid including the vessel in which
the liquid is contained, is moving at _________ with respect to the earth, but every particle of liquid have no relative motion between each other.

Answer 1

Relative equilibrium; uniform accelerated motion

Question 2

When a liquid mass is rotated about a
vertical axis at a constant speed of ω (radians
per second), every particle experiences a
________ which is equal to
𝑣2/𝑥= ω^2𝑥 where 𝑥 is the particle’s distance
from the axis of rotation.

Answer 2

normal acceleration

Question 3

tan θ is the ____________ at any distance x from the axis of rotation

Answer 3

slope at the surfaceof paraboloid
