How Does Density Affect Electrical Resistance?

AI Thread Summary
Density does not directly affect electrical resistance; instead, resistance is determined by resistivity, which is a material property. The equation R = ρl/a indicates that ρ represents resistivity, not density. Resistivity can be influenced by the material's density, but they are distinct concepts. Understanding the relationship between density and resistivity is crucial for analyzing electrical resistance in materials. The discussion highlights the importance of clarifying these terms in the context of electrical properties.

Oh dear...the rho there is not density, but the resistivity of the material. It depends on the properties of the material.

and the resisitvity of the material is depending on its own density?

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}...

Thread 'Struggle to understand the concept of the 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...
