An astronaut, while on the Earth, gives a good kick to a soccer ball. The ball lands in tę seconds after the kick. The astronaut then takes the ball to the Moon where she gives it a somewhat weaker kick. As a result, the ball reaches exactly the same maximal height it reached previously on the Earth. What statement is true about the time tm that the ball spent aloft on the Moon? (The gravity on th Moon is 6 times weaker than on the Earth. You can rely either on a direct calculation, or on a dimensional analysis or both) A. tm=36 te
B. tm=12te
C. tm=te
D. tm=(6)^1/2 te
Е. tm=6te

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
