Constant Force Force constant Web

AI Thread Summary

A spider uses sensory organs in its legs to detect vibrations in its web when prey is caught. The discussion involves calculating the force constant of the web, given that a 1.0×10-3 kg insect causes vibrations at a frequency of 15 Hz. The relationship between frequency and force constant is expressed through the formula frequency = omega/(2*PI), where omega is the square root of K/m. To find the force constant K, the mass m of the insect is used in the calculations. Understanding these dynamics is crucial for grasping how spiders interact with their environment.

Using sense organs in her legs, a spider can detect vibrations in the web when her prey is captured. When trapped in one web, a 1.0×10-3 kg insect causes the web to vibrate at 15 Hz. What is the force constant of the web?

frequency=omega/2*PI
where omega=sqrt(K/m)

u find K.
m is mass.

hope that makes sense

whoops i mean omega/(2*PI)

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 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Power of a thin lens in a medium is 1/fₘ or μₘ/fₘ ?'

Here is what I tried This question was actually asked in one of our engineering entrances. The answer was 1D. My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
