An airplane flies 700 miles with a tail wind in 2.0 hrs. if it takes 2.5 hrs to cover the same distance against the headwind, then what is the speed of the plane in still air? a).290mph b).315mph c).240mph d).330mph e).250mph

your answer would be fusion

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

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
