AI Thread Summary
The discussion revolves around calculating the number of nodal lines created by two students generating waves in a swimming pool. They are positioned 2.0 m apart and produce waves at a frequency of 1.0 Hz, with a wave speed of 0.60 m/s. The wavelength is determined using the formula V = Frequency x Lambda, resulting in a wavelength of 0.6 m. To find the number of nodal lines, the relationship between the wavelength and the distance between the students is crucial. The total number of nodal lines can be calculated based on these parameters, leading to a clear understanding of the interference pattern formed.

Homework Statement


Using a swimming pool, two students decide to test the water by setting up an interference pattern at one end of the 50 m pool. They sit 2.0 m apart and create waves by tapping their right foot, in phase with each other, onto the water at a frequency of 1.0 Hz. The speed of the waves is measured to be 0.60 m/s. The teacher is standing at the other end of the pool watching the pattern that is created and decides to count the number of nodal lines present. What is the total number of nodal lines present in the pattern generated?
i do not know the calculation for calculating the number of nodal line but i have found the wavelength

Did you calculate the wavelength with the V = Frequency x Lambda?
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
