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

What's the question here?
 
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 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
