physics doubts VERY URGENT!!!!!!!!!!!!

1.01 × 105 Pa=Hx X 1.08 × 10³ X 9.8
H=9.53m

change in h= 10-9.53=0.47

dh/h=0.47/10 X100 = 4.7%

okeks thankyou os much ))))

can sme 1 plz ans my ques about the maxima not havin a value 0
 

[astarmathsandphysics]

Is it because they are not completely out of phase or not having the same amplitude?

[nid404]

MAxima  is due to constructive interference which means waves are in phase.......
the sum of the amplitudes in this case will never be equal to zero....

ummm imade a mistake
i wanted an explanation on why the minima never has a zero value
