Question

Two forces (10+143) N and (69 +10) N act upon a body of mass 8 kg. Then the acceleration of the body is lal -2 a) (21 +3;)ms ? -2 b) (3; + 2i)ms c) (5 + 2i) ms' d) (2 +6j)ms be 2.2. î... thon its momentum in km inverse​

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
