10,000 Hz is a reasonable estimate of a frequency that can be heard by the human ear.
<h3>What frequency heard by human ear?</h3>
Humans can detect sounds in a frequency range from about 20 Hz to 20000 Hz. Lower than 20 Hz and higher than 20000 Hz can't be heard by the human ear. We can say that 10000 Hz can be hear because it comes in this range
So we can conclude that 10,000 Hz is a reasonable estimate of a frequency that can be heard by the human ear.
So we can conclude that frequency here: brainly.com/question/254161

Burning is a chemical change because when your burning something your releasing chemicals into the air ( turning it into gas , like CO2) , it requires more energy to break chemical bonds. Melting/bending your just changing the physical look of object, boiling your just heating it but the make up of the object is still the same.
here's the answer I don't know if its correct but I wish it help you thanks for the points
Answer:
a. xy
Explanation:
The Faraday's law of induction can be used to express the relationship between the electric field line integral and the magnetic flux rate change in a closed loop. In order to ensure that the relationship between the two variables is equivalent to zero, the integration should be conducted on the xy plane. The correct option is option a.
