1. The largest contribution to the mass of the atom is: 1.Higgs field providing fundamental particle mass by interacting with quarks 2.Einstein’s E = mc 2 which accounts for quark motion and interaction 3.Electric charge 4.Nuclear binding energies

2. The impact of a magnetic field on a neutron is: 1.Slows the neutron down 2.Speeds the neutron up 3.Doesn’t affect the neutron 4.Turns the neutron in a circular arc

3. Particles may be characterized as MIPs. This basically means: 1.These are maximally interacting particles with large energy loss in matter 2.Energy loss per distance traveled is minimal for MIP particles because the processes that determine the interaction depend on the particle energy 3.These are the most important particles for a particular detector to observe 4.These are the particles that arrive with greatest numbers, i.e. maximal intensity

4. The particles that typically travel the farthest in LHC detectors are: 1.muons 2.electrons 3.neutrons 4.protons

5. The underlying principle used to develop the Standard Model is: 1.Mass bends space- time 2.Charges attract or repel other charges 3.Symmetry 4.Probability
