Most workers in nanotechnology are actively monitored for excess static charge buildup. the human body acts like an insulator as one walks across a carpet, collecting - 50 nc per step.

Sometimes, when the wind blows across a long wire, a low-frequency "moaning" sound is produced. The sound arises because a standing wave is set up on the wire, like a standing wave on a guitar string. Assume that a wire (linear density = 0.

Two large crates, with masses 640kg and 490kg, are connected by a stiff, massless spring (K=8.1kN/m) and propelled along an essentially frictionless, level factory floor by a force applied horizontally to the more massive crate.
