Answer:
f = 700 Hz
Explanation:
given
amplitude =[tex]a= 7.5 \times 10^{-7} m[/tex]
speed v =[tex]3.3 \times 10^{-3}[/tex] m/s
for (a)
we know [tex]v_{max} = a\omega[/tex]
and [tex]\omega = 2\pi f[/tex]
we get
[tex]v_{max} = a( 2 \pi f)[/tex]
[tex]f = \frac{v_{max}}{2 \pi a}[/tex]
[tex]f = \frac{ 3.3 \times 10^{-3}}{ 2 \times 3.14 \times 7.5 \times 10^{-7}}[/tex]
[tex]f = 700 Hz[/tex]
