Final answer:
Wave-particle duality does not apply to macroscopic objects (false), the concept of a work function is not consistent with the classical wave model (false), and solar sails can be propelled using solar wind particles (true).
Step-by-step explanation:
True or false: wave-particle duality exists for objects on the macroscopic scale. The answer to this is false. Objects on a macroscopic scale, such as daily objects we interact with, do not exhibit wave-particle duality; this concept is primarily applicable to quantum particles like electrons and photons. The concept of a work function, or binding energy, is not consistent with the classical wave model; therefore, stating that the work function is permissible under the classical wave model is false. It is true that solar sail craft can be propelled using just particles within the solar wind. This is because solar sails are designed to capture the momentum of photons and other particles emitted by the sun, providing the thrust necessary to propel the craft through space.
