Continuum Continuum These MCQs delve into both theoretical and practical aspects of the continuum as applied in physics, emphasizing areas like fluid dynamics, spacetime, and material science. Let me know if you’d like to explore more! 1 / 10 In fluid mechanics, the continuum assumption implies that: Fluids are incompressible at all scales. Molecular interactions are ignored entirely. Fluids are treated as a collection of discrete particles. Fluids are modeled as continuous, homogeneous media. 2 / 10 In thermal physics, the continuum approach is used in defining temperature as: A property dependent only on molecular structure. A quantum mechanical operator. A property averaged over a small, macroscopic region. A discrete quantity at atomic levels. 3 / 10 The continuum approximation is crucial in analyzing: Quantum tunneling phenomena. Large-scale deformation in elastic materials. Particle collisions in a gas. Subatomic particle interactions. 4 / 10 The spacetime continuum is curved due to: The distribution of mass and energy in the universe. The presence of electric fields. The interaction of atomic particles. Uniform motion of objects 5 / 10 In the study of sound waves, the continuum approximation is valid when: Quantum effects dominate. Molecular collisions are ignored The medium is a perfect vacuum. The wavelength of the sound is much larger than the average molecular spacing. 6 / 10 In continuum mechanics, stress and strain are defined: At discrete atomic points only. Using quantum mechanical principles. As macroscopic quantities averaged over a small region. Only for isotropic materials. 7 / 10 Which physical theory treats the electromagnetic field as a continuum? Maxwell’s Electromagnetic Theory Quantum Electrodynamics String Theory Statistical Mechanics 8 / 10 The concept of spacetime as a continuum in general relativity suggests that: Space and time are independent entities. Space and time form a smooth, four-dimensional manifold. Spacetime is made of discrete quantum units. Time flows at a constant rate everywhere. 9 / 10 Which of the following equations assumes the continuum approximation in fluid mechanics? Schrödinger equation Navier-Stokes equations Maxwell-Boltzmann distribution Dirac equation 10 / 10 The continuum assumption in classical mechanics implies that: Matter is made up of discrete particles. Matter is treated as a continuous medium, ignoring molecular structure. All physical quantities are discrete.
