Answer:
Explanation:
Energy = e
mass = m
frequency = f
Amplitude = a
then,
e \propto \: {(m)}^{p} {(f)}^{q} {(a)}^{r} \\ so \\ (m {l}^{2} {t}^{ - 2} ) = {(m)}^{p}{(t)}^{ - q}{(l)}^{r} \\ since \: f \: = \frac{1}{t} \: and \: a \: have \: dimensions \: of \: length \\ so \\ p = 1 \\ q = 2 \\ r = 2 \\ so \: the \: relation \: is \\ e = k \: \cdot \: m \cdot \: {f}^{2} \cdot \: {a}^{2}
