AI Thread Summary
The discussion focuses on a 2004 AP Physics problem related to waves and sound, specifically addressing the relative phase of sound waves from two speakers at different distances. The question involves calculating the phase difference based on a wavelength of 1 meter, with one speaker 1 meter away and the other 1.5 meters away. Participants are encouraged to analyze how the difference in distance affects the sound waves' interference and resultant amplitude. Understanding these concepts is crucial for mastering wave behavior in preparation for the AP test. The discussion aims to clarify these physics principles for high school students preparing for college-level examinations.

And i am only in high school, but since the AP test is based at the college level i thought it made sense to post it here.
 
Say the wavelength is 1 m. If you are 1 m away from one of the speakers and 1.5 m away from the other, what do you know about the relative phase of the two sound waves you're hearing? What will their sum be? This should help you with part b.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
