Which of the following is a valid conversion factor? one cubic centimeter over one liter one milliliter over 100 liters 10 meters over one decimeter 100 centigrams over one gram

100 cg/1g

Step-by-step explanation:

    1 cg = 0.01 g     Multiply by 100

100 cg = 1 g

(a) is wrong. The correct conversion factor is 1000 cm³/1 L.

(b) is wrong. The correct conversion factor is 1000 mL/1 L.

(c) is wrong. The correct conversion factor is 1 m/10 dm.

catya your not at all which answer i've seen you do this on another question!

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.
