Metals are used in many products because of the characteristic properties that most metals share. which properties of the metal tungsten make it useful in the thin, glowing filaments of light bulbs? tungsten is electrically conductive, ductile, and opaque. tungsten is ductile, is malleable, and has a high luster. tungsten is ductile, has a high melting point, and is electrically conductive. tungsten has a high luster, has a high melting point, and is silver in color. metals are used in many products because of the characteristic properties that most metals share. which properties of the metal tungsten make it useful in the thin, glowing filaments of light bulbs? tungsten is electrically conductive, ductile, and opaque. tungsten is ductile, is malleable, and has a high luster. tungsten is ductile, has a high melting point, and is electrically conductive. tungsten has a high luster, has a high melting point, and is silver in color.

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.

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?
