<span>Henry Moseley established a periodic table that arranges the elements by atomic number;The atomic number increases from left to right on the periodic table;Metalloids have the characteristics of both metals and nonmetals.</span>
Answer:
0.16Hz
Explanation:
wavelength (λ) = 125 meters
speed (V) = 20 m/s
frequency (F) = ?
Recall that frequency is the number of cycles the wave complete in one
second. And its value depends on the wavelength and speed of the wave.
So, apply the formula V = F λ
Make F the subject formula
F = V / λ
F = 20 m/s / 125 meters
F = 0.16 Hz
