The sizes of the forces in each situation depend on the properties of the objects and their distances apart and, for forces between two magnets, on their orientation relative to each other. (3-PS2- 3), (3-PS2-4) • The gravitational force of Earth acting on an object near Earth’s surface pulls that object toward the planet’s center.
WebThe 5 peaks in the mass spectrum shows that there are 5 isotopes of zirconium - with relative isotopic masses of 90, 91, 92, 94 and 96 on the 12 C scale. The abundance of the isotopes. This time, the relative abundances are given as percentages. Again you can find these relative abundances by measuring the lines on the stick diagram. WebHydrogen (1 H) has three naturally occurring isotopes, sometimes denoted 1 H, 2 H, and 3 H. 1 H and 2 H are stable, while 3 H has a half-life of 12.32(2) years. Heavier isotopes also exist, all of which are synthetic and have a half-life of less …
