Why do you think some things float and some things sink?

because some things have a higher density than other things

Explanation:

some things float bc they have air inside of them which makes them rise bc air rises and gravity pulls so theyre working against each other. some things sink bc theyre heavy and gravity is already pulling them down so them being heavy just makes them sink faster. hope this helps!!!

Explanation:

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 : )
