Answer:
0.25 m/s
Step-by-step explanation:
From the question given above, the following data were obtained:
Wavelength (λ) = 0.02 m
Period (T) = 8.08×10¯² s
Speed (v) =?
Next, we shall determine the frequency of the leave. This can be obtained as follow:
Period (T) = 8.08×10¯² s
Frequency (f) =?
f = 1 / T
f = 1 / 8.08×10¯²
f = 12.38 Hz
Finally, we shall determine the speed of the leave. This can be obtained as follow:
Wavelength (λ) = 0.02 m
Frequency (f) = 12.38 Hz
Speed (v) =?
v = λf
v = 0.02 × 12.38
v = 0.25 m/s
Thus, the speed of the leave is 0.25 m/s
