(C) All of the particles bounce back at 180
(D) Most of the particles are absorbed by the foil
(E) None of the particles are deflected by more than 45


According to Bohr's model of the atom, why do atoms emit or absorb radiation only at certain wavelengths?
(A) Because the protons and electrons are distributed evenly throughout the atom
(B) Because electrons can orbit the nucleus at any radius
(C) Because electrons orbit the nucleus only at certain discrete radii
(D) Because protons orbit the nucleus only at certain discrete radii

(A) kg m/s
(B) kg m/s
(C) kg m/s
(D) kg m/s
(E) kg m/s


Which of the following is the best definition of the uncertainty principle?

(D) Light exhibits both wave and particle properties
(E) An unobserved particle can be in two places at the same time


Which of the following particles is most massive?
(A) A proton

A train at rest has a length of 100 m. At what speed must it approach a tunnel of length 80 m so that an observer at rest with respect to the tunnel will see that the entire train is in the tunnel at one time? arre train is not an electron whose parameters will change on increasing speed😆..........This cant be possible tht 100 m train become 20m unless u compress it whic is IMPOSSIBLE
