Homework Statement Two atomic clocks are synchronized. One is placed on a satellite which orbits around the Earth at high speeds for a whole year. The other is placed in a lab and remains at rest with respect to the earth. You may assume both clocks can measure time accurately to many...

Thank you both! very much appreciated :D

Homework Statement a) calculate the energy, in joules, of a quantum of light with a wavelength of 590 nm. b)will this colour be able to produce photoelectrons from the surface of a metal with a work function of 3.0 eV? Explain your reasoning. Homework Equations f=c/λ E=fh ek=hf-W The Attempt...

Thank you very much! and I honestly have no idea why I put the % haha thank you :)

Homework Statement a) Calculate the kinetic energy required to accelerate a single proton from a rest position to 0.9999c. The mass of a proton is 1.67*10^-27 Kg. b) Find the ratio of kinetic energy to the energy of a proton at rest Homework Equations Ekrest = mc2 Ek=...
