Asound is recorded at 19 decibels. what is the intensity of the sound?

79·433 × W/m²

Explanation:

Given intensity of sound in decibels is 19

Formula for intensity of sound in decibels is

where

is the intensity of sound measured in decibels

I is the intensity of sound measured in W/m²

is the intensity of the sound that is taken as standard and it's value is equal to W/m²

By applying the formula

19 = 10 × ㏒(I ÷ )

⇒ 1·9 = ㏒(I ÷ )

⇒ antilog(1·9) = I ÷

⇒ 79·433 = I ÷

⇒ I = 79·433 × W/m²

∴ Intensity of sound = 79·433 × W/m²

answer: strength i guess

explanation:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
