On paper, make a careful scale drawing of the two rhenium nuclei just after fission, and label the drawing with the distances that you just calculated. if the two rhenium nuclei are nearly touching, this would be consistent with our model of fission, in which the th-230 nucleus fissions into two pieces that are initially nearly at rest. how big is the gap between the surfaces of the two nuclei? (if you have done the calculations correctly, you will indeed find that the gap is a rather small fraction of the center-to-center distance, which means that our simple model for the fission process is a pretty good model.)

What statements accurately describe atoms

During physical science, ms. greene challenged her students to produce an energy transformation. james and jill wrapped a 4-inch nail with a coil of fifty turns of wire. they connected one end of the coil to one terminal of a knife switch. they connected the other terminal of the knife switch to the battery. finally, they connected the end of the coil to the other terminal of the battery. james held the tip of a 1-inch nail near the flat end of the 4-inch nail. jill closed the knife switch quickly and then opened it. the 1-inch nail was pulled toward the 4-inch nail. what is the best explanation of why the nail moved? a) electrical energy was converted to mechanical energy in the 1-inch nail. b) the 4-inch nail became an electromagnet and the magnetic force attracted the 1-inch nail. c) the electric current in the 4-inch nail was converted to mechanical energy in the 1-inch nail. d) the 4-inch nail had a positive charge and the 1-inch nail had a negative charge. opposites attracted.

Achlorine atom has 17 protons and 18 neutrons. what is its mass number? what is its atomic number?
