A pendulum that was originally erected by Foucault at the Pantheon in Paris for the Paris Exhibition in 1851 was restored in 1995. It has a 28.0-kg sphere suspended from a 67.0-m light cable.
How long would it take for the bob in this pendulum to move from the position of maximum displacement down to the equilibrium point? A) 4.11 s
B) 21.5 s
C) 2.58 s
D) 32.2 s
E) 42.9 s
Question 2
In a double-slit experiment, the slit separation is 1.75 mm, and two coherent wavelengths of light, 425 nm and 510 nm, illuminate the slits.
At what angle from the centerline on either side of the central maximum will a bright fringe from one pattern first coincide with a bright fringe from the other pattern?
