Answer
- All
Explanation:
Shift by which the object appears to be raised depends on these 4 factors. The shift increases with increase in refraction index of medium and also with the thickness of denser medium.

A body is in pure rotation. The linear speed $\nu$ of a particle, the distance r of the particle from the axis and the angular velocity $\omega$ of the body are related as $\omega=\frac{\text{v}}{\text{r}}$ Thus:
→-
$\omega\propto\frac{1}{\text{r}}$
-
$\omega\propto\text{r}$
-
$\omega=0$
-
$\omega$ is independent of r.
