A particle moving in one dimension (the x-axis) is described by the wave function f psi(x) = { Ae^-bx, for x > 0 Ae^bx, for x < 0 where b = 2.00 m^-1, A > 0, and the +x-axis points toward the right, Determine A so that the wave function is normalized, Sketch the graph of the wave function, Find the probability of finding this particle in each of the following regions: within 50.0 cm of the origin, on the left side of the origin (can you first guess the answer by looking at the graph of the wave function?), between x = 0.500 m and x = 1.00 m.

Match the atomic particles with their characteristics. 1. made of two protons and two neutrons neutron 2. similar to an electron; positive charge neutrino 3. orbits nucleus; negative charge positron 4. bundle of energy; zero charge proton 5. found in nucleus; positive charge meson 6. very unstable; +, -, or zero charge gamma 7. found in nucleus; zero charge electron 8. negative particle; negative charge beta 9. atomic energy converted to mass alpha

In a wind tunnel the speed changes as the cross sectional area of the tunnel changes. if the speed in a 6' x 6' square test section is 100 mph, what was the speed upstream of the test section where the tunnel measured 20' x 20'? use conservation of mass and assume incompressible flow. conservation of mass requires that as the flow moves through a path or a duct the product of the density, velocity and cross sectional area must remain constant; i.e., that ova-constant. a model is being tested in a wind tunnel at a speed of 100 mph if the flow in the test section is at sea level standard conditions, what is the pressure at the model's stagnation point? (a) the tunnel speed is being measured by a pitot-static tube connected to a u- tube manometer. what is the reading on that manometer in inches of water? (b) at one point on the model a pressure of 2058 psf is measured. what is the local airspeed at that point?

The air that we breath is made mostly of which gaseous molecule
