Answer:Thermal Energy is not a form of potential energy
Explanation:
To Solve:-
[tex]\red{➤}\:[/tex][tex]\sf ({\frac{3}{2}})^{-1}÷ ({\frac{-2}{5}})^{-1}[/tex]
[tex]\\[/tex]
Solution:-
Since the power is in negetive,we write the reciprocal of the number and then solve it like positive exponents-
[tex]\begin{gathered}\\\quad\longrightarrow\quad\sf( {\dfrac{3}{2}})^{-1}÷ ({\frac{-2}{5}})^{-1}\\\end{gathered} [/tex]
[tex]\begin{gathered}\\\quad\longrightarrow\quad\sf ({\dfrac{2}{3}})^{1}÷ ({\dfrac{5}{-2}})^{1}\quad (a^1=a)\\\end{gathered} [/tex]
[tex]\begin{gathered}\\\quad\longrightarrow\quad\sf \dfrac{2}{3}÷ \dfrac{5}{(-2)}\\\end{gathered} [/tex]
[tex]\begin{gathered}\\\quad\longrightarrow\quad\sf \dfrac{2}{3}×\dfrac{(-2)}{5}\\\end{gathered} [/tex]
[tex]\begin{gathered}\\\quad\longrightarrow\quad\sf \dfrac{2×(-2)}{3×5}\\\end{gathered} [/tex]
[tex]\begin{gathered}\\\quad\longrightarrow\quad\boxed{\sf{ \dfrac{-4}{15}}}\\\end{gathered} [/tex]
