AP Physics Multiple Choice Concept Question

AI Thread Summary
Adjusting the tension in a guitar string affects the speed of the traveling wave, which increases with higher tension. The frequency of the standing wave remains constant when the tension changes, as it is determined by the properties of the string and not the tension itself. Consequently, the wavelength will change in response to the speed increase while maintaining the same frequency. The correct answer to the question is A) 1 only, as only the speed of the wave changes with tension adjustments. Understanding these relationships is crucial for mastering wave mechanics in physics.

A standing wave pattern is created on a guitar string as a person tunes the guitar by changing the tension in the string. Which of the following properties of the waves on the string will change as a result of adjusting only the tension in the string?

1) Speed of the traveling wave that creates the pattern
2) Frequency of the standing wave
3) Wavelength of the standing wave

A) 1 only
B) 2 only
C) 1 and 2 only
D) 2 and 3 only
E) 1, 2 and 3

Well what do you think?

I think that 1) is true, because as you increase Tension, velocity should increase since the formula v=(F/(m/L))^(1/2) for the standing waves. However, I don't know whether frequency increases or wavelength as a result, or both... I don't understand this concept very well.
 

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 '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...
