Correct Answer - B
In a nuclear reaction the energy remains conservest
`P + ._(3)^(7)Li rarr 2(._(2)^(4)He)`
energy of proton `+ 7(5.60) = 2(4 xx 7.06)`
`rArr` energy of `= 17.28 MeV`

Helium nuclei combines to form an oxygen nucleus. The energy released per nucleon of oxygen nucleus is if `m_(0)=15.834` amu and `m_(He)=4.0026 `amu

Correct Answer - A `4 ._(2)He^(4) rarr _(8)O^(16)` Mass defect `=4 xx 4.0026 -15.834 a.m.u.=0.1764 a.m.u.` Total energy released `=0.1764 xx 931 `MeV Energy released /Nucleon`=(0.1764 xx 931)/(16)=10.24 `MeV

In a nuclear reactor, the number of `U^(235)` nuclei undergoing fissions per second is `4xx10^(20).` If the energy releases per fission is 250 MeV, th

Correct Answer - B (B) the fission per second `=4xx10^(20)` So , the energy relased per second `=4xx10^(20) xx250MeV ` `=4xx10^(20) xx250xx10^(6) xx1.6xx10^(-19) J` therefore , energy relased in 10 h`=...

How many head-on elastic collisions must a neutron have with deuterium nuclei to reduce it energy from `6.561 MeV` to `1 keV`?

Correct Answer - A `("Energy loss")/("Initial KE") = (4m_(1)m_(2))/((m_(1) + m_(2))^(2)) = (4(1)(2))/((1+2)^(2)) = 8/9` After `1^(st)` collision `DeltaE_(1) = 8/9 E_(0)` After `2^(nd)` collision `DeltaE_(2) = (8)/(9)E_(1)`, After `n^(th)` collision...

The binding energy of deuteron is `2.2` MeV and that of `._(2)^(4)He` is `28` MeV. If two deuterons are fused to form one `._(2)^(4)He`, th `n` the en

Correct Answer - A `2 "Deuteron rarr ._(2)^(4)He` `Q = "BE of Product" - "BE of reactant"` `= [28 MeV - 2(2.2 MeV)]` `= [28-4.4 ] = 23.6 MeV`
