Asingle sports fan is capable of yelling at an intensity level of 80 decibels from a given distance. if 10,000 similar fans were all yelling from the same distance, which of the following will be the closest to the observed intensity level?
(a) 84 decibels
(b) 120 decibels
(c) 160 decibels
(d) 320 decibels

The correct answer is part 'c' 160 dB

Explanation:

When noise levels of different intensities are superimposed the resultant intensity is given by the equation

where,

is the intensity of a general sound level

Since we have 10000 fans each producing sound of 80dB thus the resultant intensity is given using the above formula as

yup its correct its: c) b b

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
