Temperature sensing in a light bulb. incandescent lightbulbs use a tungsten wire as the light-producing filament by heating it to a temperature at which it is bright enough to produce light. the temperature of the wire can be estimated directly from the power rating and the resistance of the wire when it is cold. given a 120 v, 100 w lightbulb with a resistance of 22 w at room temperature (20c): a. calculate the temperature of the filament when the lightbulb is lit. b. what are the possible sources of error in this type of indirect sensing? explain.

It equals just about 6,300 km per hour each day an week

If you're looking for an even spread of clay, silt and sand, add a considerable amount of sand and some clay until the 3 even out". soil texture triangle. silty clay loam soil is approximately 20 percent or less sand, 25 to 40 percent clay, and 40 to 70 percent silt.

There was no intial y-momentum so the net final y-momentum must also be 0. they can have final velocities in the y-direction

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.
