The coefficient of static friction between Teflon and scrambled eggs is about 0.1. What is the smallest tilt angle from the horizontal that will cause the eggs to slide across the surface of a tilted Teflon-coated pan?
A) $0.002^{\circ}$
B) $5.7^{\circ}$
C) $15^{\circ}$
D) $33^{\circ}$
E) Other (specify)

The angle $\theta$ at which sliding begins can be found using the formula $\tan(\theta) = \mu_s$, where $\mu_s$ is the coefficient of static friction. Here, $\mu_s = 0.1$, so $\theta = \tan^{-1}(0.1) \approx 5.7^{\circ}$.
