CompoundScientists use the relative atomic mass scale to compare themasses of different atoms of elements. Atoms of carbon-12isotopes are assigned a relative atomic mass of 12 and therelative masses of all other atoms are obtained by comparisonwith the mass of a carbon-12 atom.The Avogadro constant 6.022 x 1023 is defined as the numberof atoms in exactly 12 g of carbon-12.The mole is the amount of substance that contains the samenumber of particles (atoms/ ions/ molecules/ formula unitsetc.) as there are atoms in exactly 12 g of carbon-12.Mass of 1 mole of a substance is called its molar mass.xercisesA 0.24 g sample of compound of oxygen and boron was foundby analysis to contain 0.096 g of boron and 0.144 g of oxygen.Calculate the percentage composition of the compound byweight. |

Explain different ways to induce current in a coil ? |
|
Answer» The different ways to induce CURRENT in a COIL are as follows: i) If a coil is moved RAPIDLY between the two poles of a horse-shoe magnet, then an electric current is induced in the coil. ii) If a magnet is moved relative to a coil, then an electric current is induced in the coil. FORMULA OF INDUCED CURRENT Ohm's law (V = IR) can be used to determine the induced current in the loop. Transformers are devices that INCREASE or decrease voltage based on the number of LOOPS of wire around primary and secondary coils on opposite sides of an iron core. |
