Final answer:
The questions cover various principles of physics, addressing Kepler's laws, wave-particle duality, work function, and solar sail propulsion, with true or false assessments specific to each concept.
Step-by-step explanation:
True or False Physics Questions
Question 3: A planet-satellite system must be isolated from other massive objects to follow Kepler's laws of planetary motion. True or False? The statement is false. Kepler's laws can be used to describe the ideal motion of planets and their satellites, assuming two-body interactions. In reality, multiple gravitational influences can exist, but Kepler's laws provide a first-order approximation. The presence of other massive objects does not invalidate the use of Kepler's laws but could necessitate additional considerations to account for perturbations.
Question 26: Wave-particle duality exists for objects on the macroscopic scale. True or False? This statement is false. Wave-particle duality is a concept that is primarily applied to quantum objects like electrons and photons. On a macroscopic scale, classical physics applies, and objects exhibit behaviors consistent with particles.
Question 6: The concept of a work function (or binding energy) is permissible under the classical wave model. True or False? The statement is false. The work function is a quantum mechanical concept relating to the energy needed to remove an electron from a metal surface. The classical wave model does not incorporate discrete energy levels or quantum phenomena like the photoelectric effect that demonstrate a work function.
Question 24: It is possible to propel a solar sail craft using just particles within the solar wind. True or False? The statement is true. Solar sails utilize the momentum transferred from solar wind particles and photons from sunlight to propel a spacecraft. This concept has been demonstrated in space exploration and is a practical method for propelling spacecraft without the need for onboard fuel.
