I'm certain the answer is liquid. I hope this helps you! <3
Estimates of current rates of extinction indicate that rates may be greater than extinction rates seen in the fossil records.
<h3>What is extinction of species?</h3>
Extinction of species refers to the event in which species of organisms are entirely wiped from existence either by man-made causes, natural disasters or disease.
The recent industrial age and many technological advancements by man has resulted in rapid extinction of species .
Estimates of current rates of extinction indicate that rates may be greater than extinction rates seen in the fossil records.

Answer:
0.2Hz
Explanation:
The wavelength of a radiowave can be calculated this;
λ = v/f
Where;
λ = Wavelength (m)
v = speed (m/s)
f = frequency (Hz)
Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?
Hence, using λ = v/f
f = v/λ
f = 3 × 10^8 ÷ 1.5 x 10^9
f = 2 × 10^(8-9)
f = 2 × 10^-1
f = 0.2Hz
