Question
Farmers plough the land after rains. Why?
✓

Answer

When the field is ploughed the capillaries in the soil break. As a result the underground water can be used by the plants. If the field is not ploughed the underground water would came to the surface through the capillaries and would evaporate.

For any arbitrary motion in space, which of the following relations are true?
(a) $\vec{v}_{\text {avg }}=(1 / 2)\left[\vec{v}\left(t_1\right)+\vec{v}\left(t_2\right)\right]$
(b) $\vec{v}_{ avg }=\left[\vec{r}\left(t_2\right)-\vec{r}\left(t_1\right)\right] /\left(t_2-t_1\right)$
(c) $\vec{v}(t)=\vec{v}(0)+\vec{a} t$
(d) $\vec{r}( t )=\vec{r}(0)+\vec{v}(0) t+(1 / 2) \vec{a} t^2$
(e) $\vec{a}_{\text {avg }}=\left[\vec{v}\left(t_2\right)-\vec{v}\left(t_1\right)\right] /\left(t_2-t_1\right)$
Here, 'average' means the average values of physical quantities related to the time interval $t_2$ and $t_1$.
