Question

An observer finds the angle of elevation of the top of a pole to be 60°. If the height of the pole and the observer are 25.3 m and 1.3 m respectively, find the distance between the observer and the pole.
can any one slove it in their note copy by showing a figure of this question
I will marks them as brianly and follow the correct answer one​

Answer 1

Here Work done=Heat

Current=I=10A

Time=t=10s

Potential difference=V=15V

We know

\boxed{\sf Heat=VIt}

Heat=VIt

\begin{gathered}\\ \sf\longmapsto H=15\times 10\times 10\end{gathered}

⟼H=15×10×10

\begin{gathered}\\ \sf\longmapsto H=15\times 100\end{gathered}

⟼H=15×100

\begin{gathered}\\ \sf\longmapsto H=1500J\end{gathered}

⟼H=1500J

Work done here is 1500Joules

Hey friend sorry, but I really don't know the answer
