In the possible source of error goes: Changing two variables at once to increase rate of data collection, Taking turns with lab partners performing different tasks in an experiment, Measuring millimeters with an ordinary meter stick

In the good experimental practice goes: Measuring in standard metric units, Doing repetitive trials of the same experiment, changing the angle of a ramp in an experiment by constant intervals

Explanation: hopefully this helps i got them right so it guaaranteed you will get this right aswell.

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.
