Solid-state (semiconductor) detectors operate at relatively low bias voltages and provide fast pulse response, so a solid state detector is correct.

Clinton Davisson received the Nobel Prize in 1937 for experimental confirmation of electron diffraction, so 1937 is correct.

Cohesive forces (interatomic forces) hold atoms in fixed positions, maintaining long-range order in crystals.

Binding energy per nucleon peaks near iron/medium-mass nuclei, so medium weight nuclei have the greatest values.

The Balmer first line (Hα) has wavelength 6563 Å, while the second (Hβ) is 4861 Å.

Gluons are the gauge bosons that mediate the strong (nuclear) force between quarks.

Both nuclear fission (heavy into lighter) and fusion (light into heavier) can release large amounts of energy, so either A or B is correct.

The photon has zero electric charge and zero rest mass.

Moderators commonly used in reactors include water and graphite to slow down neutrons.

Chlorine has atomic number 17, so it contains 17 protons.
