Questions about charge flow and electricity

AI Thread Summary
The discussion revolves around a student struggling with GCSE physics homework related to charge flow and electricity, specifically questions not covered in class. The student seeks resources to understand concepts like current direction, chemical compounds conducting electricity, and the production of hydrogen per coulomb of charge. Suggestions include using Wikipedia and conducting searches on relevant terms such as voltage and ions. The need for clear, informative resources is emphasized to aid in understanding these fundamental physics concepts. Overall, the conversation highlights the challenges of self-directed learning in physics.

I've just started GCSE physics. I'm pretty happy with everything on the course, but my physics teacher has given me a crazy homework which consists of simple questions about things that we haven't done in lessons. he says that we may need to research a bit, but I can't find anything with google or with bbc bitesize

The questions are ones like this:

  • The direction of the current in a metal is from the side at higher ....., to the side at lower ... This is called the .... current.
  • When some chemical compounds are... or dissolved in ... they ... electricity.

On another page they're harder than just copy and complete. For example:

  • How much hydrogen is produced per coulomb of charge flowing around the circuit? [edit] (they give an example experiment)

I really have no idea about most of this and we haven't covered it in lessons. Could anyone link me to a good informative site where this subject is covered?

Thanks

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}...
