Q. A pendulum of length 6m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 4m. (That is, 4.0 m is no longer free to swing.) How long does this pendulum take for one oscillation? Suppose that all displacement angles are small.

Q. A small immersion heater is rated at 329 W. Compute approximately how long it would take to heat a cup of soup (suppose this is 250 mL of water) from 20°C to 50°C.
