1 He 2  ... spectrum-spectrum spectrum, arrangement or display of light or other form of radiation separated according 3  ... atomic mass-atomic mass atomic mass, the mass of a single atom, usually expressed in atomic mass units (amu). ...he radius of this path depends upon the mass of the particles (all other factors, such as velocity and charge, being equal). Thus, if in the original stream isotopes of various masses are present, the position of the blackened spots on the plate makes possible a calculation of the isotope masses.
Almost all electrical appliances come for a standard voltage. Depending where you live, this is usually about 110 volts in some areas, and about 220 volts in other areas. You can take a look at a specific appliance; there is usually a metallic sticker that has the electrical specifications.
Thereâs more to know about an electric service than how to turn on a switch, thereâs things to know about amps and volts. Every electrical service has some amps and some volts; the typical average home needs 100 amps and 110-220 volts.Now that we have talked about amps and volts, letâs not forget the electrical distribution within the home.or example, an average size home with only seven circuits is much more likely to have overloaded circuits than the same home with fourteen circuits. Even if there are enough amps and volts in a home, itâs important to be able to adequately distribute the power throughout the home.
