Mr. Rollin's students attach a balloon to a straw and then tape the straw to the top of a toy car. The students inflate the balloon and
release the car and the distance the car travels is recorded in the table above. The balloon is doubled in size for four consecutive
trails.
After evaluating the results, the students predict that doubling the balloon size once more will result in the car traveling
A)
80 centimeters
B)
160 centimeters
320 centimeters
D)
A prediction cannot be made.

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.
