My best guess would be sun because it is bright but is surrounded by shadows on all sides.
To solve this question, we use the wave equation which is:
C=f*λ
where:
C is the speed;
f is the frequency;
λ is the wavelength
So in this case, plugging in our values in the problem. This will give us:
C = 261.6Hz × 1.31m
= 342.696 m/s is the answer.
Three things that effect a life system would be
- sunlight
-water
-energy/food
Hope this helps
Oxygen is a gas a room temperature.
