The answer is a) geothermal energy. I may be wrong, sorry!
120 km / 60 min
2 km / 1 min
1 km / 30 sec
0.5 km / 15 sec
0.03333 km / sec
0.03333 km = 33.33 m

Answer:
Hz
Explanation:
We know that
1 cm = 0.01 m
= Length of the human ear canal = 2.5 cm = 0.025 m
= Speed of sound = 340 ms⁻¹
= First resonant frequency
The human ear canal behaves as a closed pipe and for a closed pipe, nth resonant frequency is given as
for first resonant frequency, we have n = 1
Inserting the values
Hz
