Consider a pure-rolling race where two objects a and b are simultaneously released from the top of an inclined plane and roll down to a finish line. for each group below, answer which object will win the race or it will be a tie (a or b or tie).
1.a: 100g solid cylinder with r = 10cm vs b: 200g solid cylinder with r = 10cm.
2. a: 100g solid cylinder with r = 10cm vs b: 100g solid cylinder with r = 20cm.
3. a: 100g solid cylinder with r = 10cm vs b: 100g hollow cylinder with r = 10cm.
4. a: 100g solid cylinder with r = 10cm vs b: 100g solid sphere with r = 10cm.

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
