By what factor must the sound intensity be increased to increase the sound intensity level by 12.2 dB

the factor when the intensity of the sound increased the level by 12.2db is 16.60 times

Explanation:

The computation of the factor when the intensity of the sound increased the level by 12.2db

As we know that

10 increased its level by 10 dB

Here we used only 10dB as we are determining for 12.2dB

So

The factor should be

= 10^1.22

= 16.60 times

hence the factor when the intensity of the sound increased the level by 12.2db is 16.60 times

the closer the planet is to the sun, the larger the gravity

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
