If you move to a point twice as far away from the source, the frequency of the sound wellb twice as geat halt as great O one Sourth as great O unchanged Provide Feedback 5:30Explanation / Answer
We can answer only One question at a time( According to Chegg's Guidelines). I am answering as much as I Can. :)
Please Rate.
Answer 1: Frequency will remain Unchanged.
Answer 2: I = P/A
As we double the distance, Inew = 4**(2r)^2 = 4* (4**r^2)
Inew = 1/4 * P/A
Inew = 1/4 * I
Correct option :- (C) One forth it's original value !!
Answer 3: Frequency of A is greater than B.(Frequency is the speed of vibration of sound wave. Which decides the pitch of sound.. It can be defined as number of wave cycles occurring in a second.)
Answer 4:
Time t= 7 sec
House will be shaken due to the sound of thunder
Speed of sound v = 343 m/s
distance can be calculate using this formula
distance = speed * time
d = v*t
d = (343 m/s) ( 7 s)
d = 2401 m So, Answer will about two Kilometers away.
