In the diagram, 91, 92, and q3 are in a straight line. Each of these particles has a charge of
-2.35 x 10-6 C. Particles qı and q2 are separated
by 0.100 m and particles q2 and q3 are separated
by 0.100 m. What is the net force on particle q3?
Remember: Negative forces (-F) will point Left .
Positive forces (+F) will point Right

resonant frequency

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
