Intramolecular forces, which are still electrostatic, but because they do contain a full charge (that +1 for protons size, -1 for electrons mentioned above) but only partial charges they are considerably weaker.
The team also demonstrated for the first time that if the electrostatic actuator delivers a small mechanical force to the PMO that varies in time while the system undergoes these self - sustaining oscillations, the PMO can lock onto that tiny variable signal and greatly amplify it.
After accounting for the electrostatic repulsion and other forces, they found that the remaining force on the beads followed the force law for an ideal spring — whose force is proportional to how far it is extended — to very high accuracy.
Nanocomp Technologies, Inc., a Concord, N.H. — based maker of carbon nanotube materials, said last this week the Air Force selected the company as prime contractor for the second phase of a larger program intended to find a substitute for the nickel - based conductors currently used for electrostatic discharge (ESD) and EMI shielding.
As Titan experiences one - seventh of the gravity we experience on Earth, the electrostatic force in any structures composed of these particles — like dunes or sand castles — overcomes the force of gravity, and they refuse to slump for very long periods.
