Hey I got this question wrong on my physics test so if you could help me find the right answer and describe how you got it that'd be great. Thanks!
Homework Answers
The maximum pressure amplitude that the human ear can tolerate in loud sounds is about 28 Pa.
Therefore the maximum pressure variations the human ear can withstand are approximately 30 Pa.
Answer is 30 Pa.
pmax=BkA.
B bulk modulus
k = wave number
A amplitude
The ossicles transmit oscillation to the fluid (mostly water with bulk modulus B= 2.18x109 Pa) in the inner ear

Hey, could someone help me work out this physics-electricity problem? And would you write out your steps please? that would be a big help. thanks! Two charges of +4.0 nC and -1.0 nC are fixed to a baseline at a separation of 1.0 m. Where on the baseline should a third charge of +2.0 nC be placed if it is to experience zero net electric force?

Hi, please help me check my answers for two physics problems. If
they are wrong, please explain it so I could learn and correct the
mistake. Thank you.
[For the first problem, I got: push= 2598J, normal= 0,
weight= 0, friction= -1920J. I calculated net work to be 678J
]
[For the second problem, I got push=250J, normal and weight= 0,
friction = -200J. I calculated net force to be 50J, which is
positive]
