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.
  If it's an electric stove, check the circuit breakers. Electric ranges operate on 220 volts, mostly for the benefit of the oven. But to get that 220, two 110's are strapped together electrically. And it's with two circuit breakers.ou should check the name plate on the stove to find out the wattage of the stove. If this is not feasible then look in the manual that you got with the stove. Then use the formula, Watts = amps x volts. Amps = Watts/Volts. The voltage going to a stove is usually 240 volts.
