A-level Electron Speed

AI Thread Summary

To calculate the speed of an electron with a de Broglie wavelength of 1.3x10^-10 m, the de Broglie relation λ = h/p can be used, where h is Planck's constant and p is the momentum. The momentum of the electron can be expressed as p = mv, where m is the mass of the electron and v is its speed. Rearranging the equation gives v = h/(mλ). Using the known values for Planck's constant and the mass of the electron, the speed can be calculated. This approach is essential for understanding the wave-particle duality of electrons in quantum mechanics.

calculate the speed of an electon which has a de broglie wave length of 1.3x10^-10m

can anyone help me with this question I've never had one like this come up so i haven't a clue what to do, with only 2 weeks to my a-level exams

Have you come across the de Broglie relation
\lambda = \frac{h}{p}
for matter waves?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
