How do isobar patterns affect winds

Closely spaced isobars indicate large pressure changes over a small area, causing wind speeds to increase. Isobars also determine wind direction, with winds blowing clockwise around highs and counterclockwise around lows in the Northern Hemisphere.

hope this helps :)

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

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
