Tension and Fundamental frequency

AI Thread Summary
The discussion focuses on the relationship between tension and fundamental frequency in a uniform wire carrying AC current. It notes that a graph plotting the square root of tension against the length between nodes reveals key insights about the wire's behavior. Using a wire with a smaller diameter would likely increase the fundamental frequency due to reduced mass per unit length. Increasing the current could also raise the frequency, as it may enhance the tension in the wire. However, switching to a DC current would prevent the formation of standing waves, resulting in no observable fundamental frequency.

The fundamental frequency of a uniform wire with an AC current of constant magnitude was found at various different tensions and a graph of (T1/2,l) was plotted (l was the length between the two nodes of the wire when the fundamental frequency was found). How would the data on the graph (including gradient) be affected by a) using a wire of smaller diameter, b) increasing the current or c) using a DC current of the same constant magnitude?

I've already written down how far I got (in terms of the experiment which I set up and decided to plot with that graph) but I really don't know how to start with this question. I know that c), using a DC current would yield no results of fundamental frequency as no standing wave is formed at all. Any help appreciated :)

I think if you expect any responses you might have to describe the experiment more fully.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
