Target entity: Cavendish experiment on the density of the Earth
Context triple: [Henry Cavendish, notableWork, Cavendish experiment on the density of the Earth]
  • A. Cavendish experiment chosen
    The Cavendish experiment was an 18th-century physics experiment by Henry Cavendish that measured the tiny gravitational attraction between lead spheres, allowing the first calculation of the gravitational constant and the mass of the Earth.
  • B. Ives–Stilwell experiment
    The Ives–Stilwell experiment is a classic test of special relativity that measured the relativistic Doppler effect to confirm time dilation for fast-moving ions.
  • C. Trouton–Noble experiment
    The Trouton–Noble experiment was an early 20th-century test of the luminiferous aether that searched for a torque on a charged capacitor in motion and, by finding no such effect, provided support for the emerging theory of special relativity.
  • D. Michelson–Morley experiment
    The Michelson–Morley experiment was a landmark 1887 physics experiment that attempted to detect the Earth's motion through the hypothesized luminiferous aether and whose null result helped pave the way for Einstein's theory of special relativity.
  • E. Kennedy–Thorndike experiment
    The Kennedy–Thorndike experiment is a classic test of special relativity that examined the constancy of the speed of light using an interferometer with unequal arm lengths and varying laboratory velocity.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
