Why can humans NOT hear the sound produced by a bat?
The frequency of bat sounds is above 20,000 Hz.
The human ear can hear sounds only in the audible range of about 20 Hz to 20,000 Hz.
Bats produce ultrasonic sounds (ultrasound), whose frequency is higher than 20,000 Hz, and use their echoes to locate obstacles and prey (echolocation).
Sounds below 20 Hz are infrasonic, which is not what bats produce; loudness does not make a sound inaudible, and bat sounds travel through air, not only water.
Hence, the answer is the frequency of bat sounds is above 20,000 Hz.

- The velocity v(x) of a particle moving in one dimension is given by v(x) = v 0 sin \(\rm\left(\frac{\pi x}{x_0}\right) \) , where v 0 and x 0 are positive constants of appropriate dimensions. If the particle is initially at x/x 0 = ϵ, where |ϵ| ≪ 1, then, in the long time, it
The position of a particle in one dimension changes in discrete steps. With each step it moves to the right, however, the length of the step is drawn from a uniform distribution from the interval \(\left[ {{\rm{λ }}\,{\rm{ - }}\,\frac{{\rm{1}}}{{\rm{2}}}{\rm{w,}}\,{\rm{λ }}\,{\rm{ + }}\,\frac{{\rm{1}}}{{\rm{2}}}{\rm{w}}} \right] \) , where λ and w are positive constants.
