The duration required for the stone to reach the ground.
\(t=\sqrt{\frac{2 L}{g}}+\frac{L}{C}\)
Here,C represents the speed of sound.
Now, differentiating the above equation
\(\frac{d t}{d L}=\sqrt{\frac{L}{g}} \times \frac{1}{2 \sqrt{L}}+\frac{1}{C}\)
\(dL =\frac{ dt }{\frac{1}{\sqrt{2 gL }}+\frac{1}{ C }}\)
We hat dt=0.01
\(\Rightarrow \frac{ dL }{ L } \times 100=\left(\frac{ dt }{\frac{1}{\sqrt{2 gL }}+\frac{1}{ C }}\right) \frac{1}{ L } \times 100\)
\(=\frac{15}{16 \%} \approx 1 \%\)
The physical world includes the complications of the natural world around us. It is a type of analysis of the physical world around us to understand how it works. The fundamental forces that control nature are:
