For an inviscid fluid we have euler's equation (vectors are denoted by bold characters) )= vp - vgx + v xu at and whether or not the fluid is incompressible, we also have the conservation of mass dp +pv u 0. dt show that x vp dt deduce that, if p is a function of palone, the vorticity equation is exactly as in the incompressible, constant density case, except that ois replaced by ap.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy

Each line (unit) on the horizontal axis represents: 5 years 10 years 20 years all of the above

Estimate the magnitude of the electric field due to the proton in a hydrogen atom at a distance of 5.29×10 to the power of −11 m, the expected position of the electron in the atom.
