@ikram002p here you go

Answer 4

\(T \text{ }\alpha \text{ } \dfrac{1}{w}\)
means
\(T \text{ }= \text{ } \dfrac{k}{w}\) s.t k is constant

\( \dfrac{1}{9} \text{ }= \text{ } \dfrac{k}{3}\)
so \(k=\dfrac{1}{3}\)


equation become
\(T = \dfrac{1}{3w}\)

Answer 5

so
\(T = \dfrac{1}{3w}\)
\(\dfrac{1}{243} = \dfrac{1}{3w}\)

solve for w
