    Undergrad Calculating Photon Energy Needed to Exceed Fused Silica Glass Band Gap

    Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. This works through a process known as multiphoton absorption. In this process, several photons are absorbed at the same time. If very...

    Relativistic Length Contraction in Three-Spacecraft Chase Scenario

    Three enemy spacecraft have been causing trouble in the asteroid belt. They always travel in a line, evenly spaced apart, attempting to chase down local spacecraft to steal their goods. The local asteroid colonists have decided to set a trap to capture these three spacecraft . They'll get...

    What is the speed of the missile, relative to ship B?

    Two spaceships, named A and B, are flying toward each other with relative speed .80c . The captain of ship B knows that ship A uses 2-m-long missiles. She measures the length of the first missile, once it has finished accelerating, and finds it to be only 0.872m long. What is the speed of the...

    Undergrad Does Pipe Diameter Affect Water Flow Rate?

    Consider the following water circuit: water is continually pumped to high pressure by a pump, and then funnelled into a pipe that has lower pressure at its far end (else the water would not flow through the pipe) and back to the pump. Two such circuits are identical, except for one difference...

    Measuring Temperature Using a Carbon Resistor

    A carbon resistor is to be used as a thermometer. On a winter day when the temperature is 4.00(Degree C.), the resistance of the carbon resistor is 218.0(Greek "w') . What is the temperature on a spring day when the resistance is 215.8(Greek "W")? Take the temperature coefficient of resistivity...
