Can you help me and check my answers here?
1 is wrongProtons and neutrons ARE hadronsThey're made up of up quarks and down quarks6 is right, but I'd say incompleteA thick enough layer of all three of those items will stop beta particlesBeta particles have a range based on the amount of matter they can penetrateAluminum happens to be denser than paper, and both are denser than airSo all three will stop beta particles, but aluminum foil will stop beta particles that would make it through the same thickness of paper or air10 is wrongA nucleon is a particle found in a nucleus - a neutron or a proton - not a particle that makes up a neutron or proton11 is wrongThe first choice is the beta particle The mass number stays the same on both sides of the arrow - 59 The atomic number of the daughter product increases by one, indicating an increase in positive chargeThe particle emitted carries a charge of -1 to keep the charges in balanceThis is an electron, which is the same thing as a beta particle14 is wrongA radioisotope thermal generator uses the heat from radioactive decay to provide electricityThe third choice shows the radioactive decay of plutonium, which is what is typically used for a thermal generator15 is wrongTechnically, the right answer is not one of the choices givenThe up quark has a charge of +2/3The down quark has a charge of -1/3If the question is looking for the absolute magnitude of a charge, down quark would be the right choice, but the test writer should lose some points here:-) 19 - I can't get the image to loadSince the word reaction is used, we can rule out medical X-ray deviceIf it just shows a simple decay, it would be the radioisotope thermal generatorIf it shows light atoms combining with each other with heavier atoms resulting, that's a fusion reactorIf it shows heavy atoms breaking apart, and especially if it shows neutrons from the reaction hitting other nuclei and triggering fission there, that's a fission reactor.
