AI Thread Summary
The discussion centers on the term "tubes" in the context of a capacitor experiment involving a dielectric made of tap water. Participants seek clarification on what "tubes" refers to in the formula C=E[N(t)/N(v)], specifically regarding N(t), which represents the number of connections between conductors. The lab involves measuring electric potentials and drawing electric field lines, using two conducting objects connected by alligator clips. Understanding the concept of "tubes" is crucial for applying the formula correctly in the experiment. The inquiry emphasizes the need for clarity on this terminology to proceed with the lab work effectively.

"tubes" in capacitor

Homework Statement



question is: what are tubes in capacitor?
or...
tubes connecting the conductors?

I'm supposed to find number of tubes...

During a "Equipotentials and Electric Field lines" Lab
where I create a Capacitor-like settings and measure the different potentials at different location. tap water inside a large, broad bowl is used as dielectric of capacitor...then electric field of the water is drawn. (AC source was used, Two conducting objects that are connected by alligator clip was placed on the bowl).

I need to apply this formula for my lab
C=E[N(t)/N(v)]

and it said "N(t) is the number of 'tubes' connecting the conductor.

What do they mean by tubes?

Homework Equations


C=E[N(t)/N(v)]

(E stands for EMF voltage
N(t) is number of delta V's between conductors
N(t) is number of "tubes" connecting the conductor.

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}...
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...
