Emission of a and b -rays bring some changes in the nucleus of the atom and the new element formed as a result of these charges is called daughter element. There is conservation of both atomic number and mass number in the equation of a nuclear reaction. Thus, i) Sum of the mass numbers o..

An isosceles trapezoid of parallel sides 60 cm and 30 cm is revolved about its longer side. The non-parallel side is 25 cm each. Find the volume of the solid so formed. [Take π = 3.14] => 32000 π cubic cm or 16100 p cubic cm or 16050 p cubic cm or 16000 π cubic cm..
