Adriver realizes that she is traveling in the wrong direction on a one-way street. she has already driven 3.5
meters at a velocity of 16 meters per second, cast before deciding to make a u-turn. how long did it take for
the driver to realize her error?

Driver take 0.22 second to realize error.

Explanation:

Given data:

Distance = 3.5 m

Velocity = 16 m/s

Time taken = ?

Solution:

Time = displacement / velocity

t = d/v

Time = 3.5 m/ 16 m/s

Time = 0.22 s

Driver take 0.22 second to realize error.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
