Austin builds three pinewood derby cars. car a weighs 5 ounces, car b weighs 6 ounce, and car c weighs 7 ounces. he predicts that the more weight added to a car leads to a faster finish. scientific conclusions are based on scientific evidence, what evidence would support austin’s prediction?

He could race multiple cars with different weight added on them and do multiple races (just to be sure) and see if his theory was correct, if not he should right down what he has learned from his experience! :D

-You'll never learn if u don't try ;)

A) cave formation rates

Explanation:

The carbon dioxide in the earth atmosphere is being increasing due to the human activities such as deforestation, and burning of the fossil fuels. The carbon dioxide in the air get mixed with the rain water which seeps into the soil. It results in the accumulation of carbonates in the soil in the form of limestone. The cave of limestone is formed by the groundwater because limestone is a soft material which get easily dissolves in the water.
