If there were no gravity, which of the following will not be there for a fluid?

Correct answer: C. Pressure

  • A. Viscosity
  • B. Surface tension
  • C. Pressure
  • D. Archimedes' upward thrust

Explanation

The correct answer is Pressure. In a fluid, pressure is the result of the weight of the fluid acting on a given area, which is directly influenced by gravity. Without gravity, the fluid would not exert the weight-induced pressure that we typically measure.Viscosity is a measure of a fluid's internal resistance to flow and is determined by intermolecular forces, not gravity.Surface tension arises due to the cohesive forces between liquid molecules and is not directly dependent on gravity.Archimedes' upward thrust or buoyant force is indeed related to gravity, as it involves the weight of the displaced fluid. However, the concept of buoyancy can be considered in different contexts, such as zero-gravity environments, where the definition of weight changes, but the idea of displacement remains.

About Fluid Dynamics

Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
