Which sound has waves with the greatest amplitude?

noisy classroom

jet takeoff

loud music

light whisper

Jet takeoff sound has waves with the greatest amplitude.

Option: B.

Step-by-step explanation:

The sound intensity is measured in decibels and sound intensity is directly proportional to Amplitude.

Thus if the decibel increases, then the amplitude will also get increased.

From the given graph we have the respective data

Decibel of Jet Takeoff = 100 dB.

Decibel of Light Whisper = 10 dB.

Decibel of Noisy Classroom = 60 dB.

Decibel of Loud Music = 80 dB.

Thus among these Jet takeoff has the highest decibel amount.

So the amplitude of the Jet Takeoff's Sound wave will be the greatest among other three sound waves.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
