Fluid statics is the physics of stationary fluids. Conceptual Questions 1. What physical characteristic distinguishes a fluid from a solid? 2. Which of the following substances are fluids at room temperature: air, mercury, water, glass? 3. Why are gases easier to compress than liquids and ...
In addition to its use in physics, the termfluxappears in other fields, including medicine (fluids passing through or from a body), fluid dynamics (the flow of water in a stream), metalwork (a substance used to bond metals during soldering or welding), computing (as both an open source ...
What is a lever in physics?Simple Machines:Simple machines are machines that do work in one motion. Machines make work easier by being able to multiply force, or gain distance, at the expense of the other quantity. The six types of simples machines are: lever, ramp, wedge, screw, pulley...
In contrast, the viscosity of non-Newtonian fluids is not constant, but rather varies greatly depending on the force applied. A classic example of a non-Newtonian fluid isOobleck(sometimes called "slime," and often made in elementary school science classes), which exhibits solid-like behavior wh...
When a star is composed of perfect fluid (in the sense that it’s energy momentum tensor is described by the density and the pressure), one form of matter, the solution of the gravity equation can be written as, ds2=−B(r)dt2+A(r)dr2+r2(dθ2+sin2θdϕ2),(1) with A(...
What is fluid? Show that fluid exerts pressure and prove that the force acting on a fluid in equilibrium at rest have to be perpendicular to its surface. View Solution The diagram given below is that of a structure present in a human kidney. Study the same and answer the questions that...

In physics, a fluid is a liquid, gas, or other material that continuously deforms under an applied shear stress, or external force. They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them. ...
Wherever a loose bed of sand is subject to sufficiently strong winds, aeolian dunes form at predictable wavelengths and growth rates. As dunes mature and coarsen, however, their growth trajectories become more idiosyncratic; nonlinear effects, sediment s
Let's do some math to explain my purpose more accurately! Let's start from basics of the physics and in my opinion that would be the first equation in the classical thermodynamics as equation of state. We assume: there is a fluid, which have a equation of state as: ρ=ρ...
