Question 1: Properties of Matter

Question

If a small orifice is made at a height of
0.25 m from the ground, the horizontal
range of water stream will be

Accepted Answer

Given, Height of small orifice from ground
$$(HÃ¢ÂÂh) = 0.25$$ m
Total height of water tank,
$$(H)=1 \mathrm{~m}$$
$$	herefore$$ Range of water stream,
$$\begin{aligned}
R & =2 \sqrt{h(H-h)}=2 \sqrt{(H-0.25)(0.25)} \\
& =2 \sqrt{(1-0.25) 0.25}=2 \sqrt{0.75 	imes 0.25} \\
& =0.866 \mathrm{~m}=86.6 \mathrm{~cm}
\end{aligned}$$
