Sound Pressure Calculations for a Baby and Parents

AI Thread Summary
To calculate the difference in sound intensity levels heard by the father and mother, the distances from the baby to each parent must be used in the sound intensity equations. The intensity for each parent can be calculated using the formula I = p / 4π(d^2), where p is the sound power and d is the distance. After determining the intensities, the sound levels in decibels can be found using B = 10 log(I/I_o). The final step involves finding the difference between the two sound levels, B2 - B1. This calculation will provide the required difference in sound intensity levels experienced by the father and mother.

Homework Statement


A baby's mouth is a distance of 35.0 cm from her father's ear and a distance of 1.52 m from her mother's ear.

Child Sounds <------------0.35m-------->Father
X <----------------------------1.52m-----------------> Mother


Homework Equations


I(Father) = p / 4pi(d^2)
I(Mother) = p/ 4pi(d^2)

B1 = 10 log(I1/I_o)
B2 = 10 log(I2/I_o)

B2 - B1

Sorry, the question is:

What is the difference between the sound intensity levels heard by the father and by the mother?
 
Does anyone know how to start this problem?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
