Net force=
where
is the elongation, L is original length,
is the angular velocity
Substituting the equation of
into the above we obtain
Answer:
allows for better thermal equilibrium
Explanation:
Due to the cone shape, most of the liquid will be closer to the bottom than the top. The large surface area of the bottom allows for faster heating.
