Question

a circle of diameter50 mm rolls for a distance of 180 mm along a straight line draw the locus of a point lying on the circumference of the circle name the curve traced ​

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
