Grade K-12 Explained: What It Is & What It Means

AI Thread Summary
Grade K-12 refers to the educational system encompassing kindergarten through 12th grade, covering the years before college and after preschool. In the UK, the equivalent of 12th grade is referred to as year 13, typically for students aged 17 to 18. The discussion raises the possibility of younger students, such as those in K-5, seeking help with basic academic questions. However, the site rules require users to be at least 13 years old, which limits direct participation from younger students. The conversation highlights the potential for parents to seek assistance for their children’s educational needs.

I really have no clue what grade K-12 means..

Kindergarden through 12-th grade. (everything before college and after pre-school)
 
The final year at our schools in the UK are for 17/18 year olds. We call them year 13s, so I suppose that is 13th Grade?
 
i wonder if we would seriously expect to get K through 5 or 6 level questions on this board... imagine if we had 8 years olds asking us for help to multiply 2 digit numbers...

or kindergartners asking for help to learn how to read

chuckles.

Especially since the site rules specifically state that one must be at least 13 years old to join!
 
Yeah, but kids do ask tricky questions, don't they? So there might be some parents looking for help...

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...
