Answer:
The final kinetic energy is
Explanation:
From the question we are told that
The electric field is
The charge on the object is
The mass of the object is
The distance moved by the object is
The workdone on the object by the fields is mathematically represented as
Now this workdone is equivalent to the final kinetic energy so
substituting values
Given that,
Frequency emitted by the bat, f = 47.6 kHz
The speed off sound in air, v = 413 m/s
We need to find the wavelength detected by the bat. The speed of a wave is given by formula as follows :
or
So, the bat can detect small objects such as an insect whose size is approximately equal to the wavelength of the sound the bat makes i.e. 8.67 mm.
