AI Thread Summary
To calculate the minimum uncertainty in the momentum of an electron, the Heisenberg uncertainty principle is essential. This principle states that the product of the uncertainties in position and momentum is at least a constant value (h/4π). Given the uncertainty in position of 1x10^-10m, one can rearrange the formula to find the corresponding uncertainty in momentum. Understanding this relationship is crucial for solving the problem effectively. Familiarity with the Heisenberg uncertainty principle is necessary for tackling such questions.

I am having a real problem understanding what I'm supposed to do for this question:
The position of an electron (mass given) is located by a detector with an uncertainty of 1x10^-10m, calculate the minimum uncertainty in the momentum of the electron.

Now, I have no idea how to calculate uncertainty, I can't find it in my book and I can't even find it online, is there some way anyone can explain how I am supposed to calculate uncertainty? I'm not looking for an answer just how I should go about doing this.

Thanks

Well you should have learned the Heisenberg (forgive me if i spelled his name wrong) uncertainty principle if you were given a question like that.
 

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}...
