Label method for converting units (dimensional analysis) label method of unit a very useful method of converting one unit to an equivalent unit is called the factor conversion. you may be given the speed of an object as 25 km/h and wish to express it in m/s. to make this conversion, you must change km to m and h to s by multiplying by not want will cancel out and the units you want will emain, conversion factors: 1000 m -1 km and 3600 a series of factors so that the units you do seconds# 1 hour do the following conversions using t he factor-label method. include units in each step and box in your 7. how many meters are in 100 feet?

Tungsten-filament lightbulb emits light based on the temperature of the filament. which phenomenon does this demonstrate?

Anybody wanna ? (picture included? )

The inside surface of a cylindrical-shaped cave of inner diameter 1.0 m is continuously covered with a very thin layer of water. the cave is very long and it is open on both ends. the water on the cave surface is at a constant temperature of 15.5 °c. the cave is constantly exposed to wind such that 15.5 °c air flows through the cave at 4.5 m/s. the kinematic viscosity of the air is 14.66 x 10-6 m2/s and the molecular diffusion coefficient of water vapor in the air is 0.239 x 10-4 m2/s. because the cave diameter is so large, the flow of wind down the length of the cave, in the x direction, can be treated like it is external flow and the cave surface can be approximated as flat where appropriate. calculate the x value, in a) the transition to turbulent flow occurs at rex meters, where the air flow transitions from laminar to turbulent along the inside surface of the cave b) calculate the x value, in meters, where the bulk steady state concentration of water vapor in the air flowing in the cave is 10% of the saturation concentration. assume the air at the surface of the water layer is 100% saturated with water vapor. assume the wind entering the cave contained no moisture before it entered the cave. take into account the transition from laminar to turbulent flow when solving part b
