We find out why the Hindenburg airship was tragically filled with hydrogen, not helium; ... Web3 jun. 2024 · So the reactions involved in nucleosynthesis have been studied in the laboratory, and the cross section for, say, a proton and a neutron to form deuterium, and the cross section for deuterium and a proton to form Helium-3 are known. The last piece of the puzzle is knowing the baryon density at that time after the Big Bang.
WebAll the densities are equal. A plastic ball with a volume of 19.7 cm3 has a mass of 15.8 g. Would this ball sink or float in a container of gasoline? It would sink because the density of the ball, 0.802 g/cm3, is greater than the density of gasoline. What is the volume, in cubic centimeters, of a sample of cough syrup that has a mass of 50.0 g? WebIn equation form, Archimedes’ principle is. F B =wfl, F B = w fl, where F B F B is the buoyant force and wfl w fl is the weight of the fluid displaced by the object. This principle is named after the Greek mathematician and inventor Archimedes (ca. 287–212 BCE), who stated this principle long before concepts of force were well established.
