Question

Transform the following into the mathematical form:

(i) The mass (m) of the iron block, has direct variation with its volume (v).
(ii) The area (A) of the circle is proportional to square of its radius (r).
(iii) The pressure (p) of the liquid is directily proportional to depth (d) of the liquid.

Answer 1

$$\begin{gathered} \left(\mathrm{i}\right)m\mathrm{\alpha }v \\ \left(\mathrm{ii}\right)\mathrm{A}\mathrm{\alpha }{r}^2 \\ \left(\mathrm{iii}\right)p\mathrm{\alpha }d \end{gathered}$$
