Hmm... The question hadn't specified de broglie wavelength- hence my confusion as to whether I would use de Broglie's relationship or just Planck's equation. I thought Planck's equation only pertained to EM radiation?

This is not a specific question; I'm just unclear about a concept. Homework Statement Given the kinetic energy of an electron emitted, how would you find the wavelength? Homework Equations E=h*frequency or E=0.5mv2 The Attempt at a Solution I'm thinking I would use the...

Homework Statement A 34g bullet traveling at 120m/s embeds itself in a wooden block on a smooth surface. The block then slides toward a spring and collides with it. The block compresses the spring (k=99N/m) a maximum of 1.2 cm. Calculate the mass of the block of wood. Homework Equations...

Ah, I understand now. Thank you!

Hi! I have an assignment to write a mini-essay of sorts on Atwood's machine. One of the things I need to cover is how to find the value of g by using Atwood's machine. I really have no idea how to do this. I was thinking about rearranging a= [(m2-m1)g] / (m1+m2) but I don't understand how to...
