Blank is the amount of energy in a sound wave per unit of time and is also related to the loudness of a sound

acoustic power

Explanation: A sound wave is a mechanical wave, so the energy is related to the intensity and the frequency of the same. The rate of "sound energy" as a function of time is called the "sound power" or "acoustic power" which is the rate at which sound energy is emitted or received.

If the acoustic power increases in a given point in space, this means that the point is receiving more sound energy, and then the loudness of the sound also increases at that point.

the answer is:

in a biology class, the teacher started explaining a new lesson about the dna structure. personally, i found this lecture hard to understand. so i decided to use my critical thinking skills to be able to understand it. i analysed the different ideas, and broke them down into smaller parts to assimilate each. then i started evaluation and tried to link what i am learning with real life experiences so that i can make sure that i know how everything i am learning relates. finally, i started questioning by researching more what i learned and asking more questions that can me through my learning process. reflecting on the information meant that i should review it. all this me greatly understand what i previously found hard to understand.

hope it !
