Can someone explain why the answer is A?
Mass will get coverted to energy
Mass difference = 238.050786 - 234.043583-4.002603 u
= 0.0046 u
So, E = mc^2
m = 0.0046u = 0.0046*931.494 MeV/c^2
= 4.28 MeV/c^2
So, E = mc^2 = 4.28 MeV
So, Option A is correct

(1 point) A Uranium-238 nucleus (U-238) decays to a Thorium-234 (Th234) by emitting an alpha particle (i.e. a Helium-4 nucleus): 1,228 +Th%d4 + He A Uranium nucleus has 92 protons in it while a Helium nucleus has 2 protons. The mass of a Helium nucleus is 6.645 x 10-27 kg. For this problem assume that the Uranium nucleus is initially at rest and the Thorium nucleus remains at rest after the decay. If the alpha particle is initially at rest...
When a stationary plutonium-239, 239/94 Pu, decays into uranium-235 plus an alpha particle, the energy released in the process is 5.24 MeV. The following masses are known: 4/2 He: 4.002603 u 235/92 U: 235.043924 u What is the mass of the 239/94 Pu nucleus, in amu? (1 u = 931.494 MeV/c2)
A uranium-238 atom can break up into a thorium-234 atom and a particle called an alpha particle, α-4. The numbers indicate the inertias of the atoms and the alpha particle in atomic mass units (1 amu = 1.66 × 10^−27 kg). When an uranium atom initially at rest breaks up, the thorium atom is observed to recoil with an x component of velocity of -2.6 × 10^5 m/s. How much of the uranium atom's internal energy is released in the...
