24. You and two friends apply a force of 425 N to push a piano up a 2.0 m long ramp.
a. Work How much work, in joules, has been
done when you reach the top of the ramp?
b. Power If you make it to the top in 5.0 s,
what is your power output in watts?
c. Mechanical Advantage If lifting the piano
straight up requires 1,700 N of force, what is
the mechanical advantage of the ramp?

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
