A. What was your hypothesis? According to your data, do you think your hypothesis was correct? b. What is a half-life?
c. When does a radioactive sample emit the largest number of decay particles? Why is this information important? (How can it be applied in our world today?)
d. Do you think the shape of the curve on your graph would change if you increased the half-life to 20 seconds? What does this reveal about radioactive decay?
e. Do you think the shape of the curve on your graph would change if you started with a smaller sample, say 50 atoms (pennies)? What does this reveal about radioactive decay?

Aman throws a football straight into the air. as it rises, it slows down. which type of energy is the football gaining?

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
