Series of Wave Equation problem

AI Thread Summary
To find the distance between a point at the crest of a wave and a corresponding point four crests away, the wavelength must first be calculated using the equation V = λ * F, where V is the wave speed (200 m/s) and F is the frequency (50 Hz). This results in a wavelength (λ) of 4 meters. Since four crests correspond to four wavelengths, the distance between the two points is 4 wavelengths multiplied by the wavelength, totaling 16 meters. Therefore, the distance between the two points is 16 meters. Understanding the relationship between wave speed, frequency, and wavelength is crucial for solving wave-related problems.

A series of waves traveling at 200m/sec are being generated by a 50hz source. A point at the very top of the crest of a certain wave is ? meters away from a corresponding point 4 crests away.

The only equation I have is V=lambda*F. Is there a way to get the distance w/ this or am I missing something?

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 .

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 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
