What is the sound intensity level in decibels of ultrasound of intensity 7.53 ✕ 104 w/m2, used to pulverize tissue during surgery?

Answer : The intensity of sound level in decibels is, 169 dB

Explanation:

The expression used for the intensity of sound level is given by the equation:

where,

I = final intensity =

= initial intensity = threshold intensity of human hearing =

Now put all the given values in the above formula, we get:

Thus, the intensity of sound level in decibels is, 169 dB

it is a solid

explanation:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
