Human ear can hear the lowest frequency about 20 Hz, this is 20 vibrations per second. Vibrations of pendulum are very small and frequency is less than 20 Hz, so we can't hear it.

It does, but the sound is at a frequency that's too low for you to hear.
If you could build a pendulum short enough so that it made 20 or more
complete swings every second, THEN you'd begin to hear sound from it.

Which of the following statements about diffusion is true?

polet [3.4K]

Answer:

3. It is a passive process in which molecules move from a region of higher concentration to a region of lower concentration.

Explanation:

Diffusion can be defined as the movement of solute or gaseous molecules from the region in which they have higher concentration to the regions in which they have lower concentration until they become evenly distributed across the two regions.

Diffusion is a passive process, that is, it requires no energy.

Option 3 is the correct option.
