Calculate for how many years the fusion of 2.0 kg deuterium will keep 800 W electric lamp glowing. Take the fusion reactants as:
`"_1^2H+_1^2Hrarr_0^1n+3.27MeV`

How long can an electric lamp of 100W be kept glowing by fusion of 2.0 kg of deuterium? Take the fusion reaction as ("_1^2H) + ("_1^2H) rarr ("_2^3He) + n + 3.27 MeV

Calculate and compare the energy released by fusion of 1.0 kg of hydrogen deep within Sun.

How many 7-digit numbers can be formed, using the digits 1, 2, 0, 2, 4,2 and 4?

Consider the D–T reaction (deuterium–tritium fusion) "_1^2H + "_1^3H rarr "_2^4He + n . Calculate the energy released in MeV in this reaction from the data: m( "_1^2H )=2.014102 u m( "_1^3H ) =3.016049 u
