digital camera???

Explanation:

A graduated cylinder's purpose is to measure or mix substances. A digital camera- well, that's uh, pretty self explanatory o.o

A digital thermometer is used to determine the temperature of a substance. A balance scale is used to measure the weight of an object.

I think the best option is digital camera because with this, you can observe the color and texture of an object, even without feeling it, like you can visually see if an object has a rough or smooth texture.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
