A pendulum of length 2.0 m is held out to point A (see diagram below). At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 0.50 m. (That is, 0.50 m is no longer free to swing.) How long does this pendulum take for one oscillation? Assume that all displacement angles are small.
Using your value for n, find the speed of light inside the lucite rectangle. what will be the wavelength of the light inside the material
A saturated solution of strontium hydroxide is prepared in the excess solid Sr(OH)2 is allowed to settle. A 25.0mL aliquot of the saturated solution is withdrawn and transfer to an Erlenmeyer flask
A radio can be tuned into a particular station frequency by adjusting the capacitance in an L-C circuit. What is the inductance L of a coil connected to this capacitor if the oscillation frequency of the L-C circuit is 1.69MHz
You are designing a pendulum clock whose period can be adjusted by ±10% by changing the length of the pendulum. Determine the range of change of length which provide this flexibility in the period
An airline passenger dangles her watch from a string while the jet takes off. The string makes an angle of 25o with respect to the vertical while the aircraft accelerates for takeoff, which takes about 18 seconds. Determine the takeoff speed of the a..
An important feature of the Carnot cycle is that: A) its efficiency can be 100% B) its efficiency depends on the absolute temperature of the hot reservoir used.
