A)the triple-alpha process is a nuclear fusion process in stars by which three helium-4 nuclei combine to produce a nucleus of carbon-12. given that the binding energy per nucleon of helium-4 is 7.074 mev and the binding energy per nucleon of carbon-12 is 7.680 mev, how much energy is released by each instance of this process? b)in a fission process, a nucleus of u (a-235, z-92) is struck by a free neutron and produces a nucleus of sr (a-90, z-38) along with three free neutrons. what are the mass number and atomic number of the other nuclide produced in the fission?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

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
