An elevator has a massif 1000 kg what is the tension force on its cables when it is stationary

T=10000N (g=10 ms2)

If elevator is hanging from the cable a non contact force 'mg' is acting on it in downward direction .If the is cable is able to hold the lift in air then it would require force greater than or equal to force of gravitation i.e, 'mg' in opposite direction to prevent it from falling and counter balance force of gravitation i.e,'mg'. Now if force applied by cable is greater than 'mg' it will move up with some initial acceleration.But as lift is rest only force required will be equal to'mg'.

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
