Which statement describes why energy is released in a nuclear fission reaction based on mass-energy equivalence? for large nuclei, the mass of the original nucleus is greater than the mass of the products. for large nuclei, the mass of the original nucleus is less than the mass of the products. for small nuclei, the binding energy of the lighter nuclei is greater than the binding energy of the heavier nucleus. for small nuclei, the binding energy of the lighter nuclei is less than the binding energy of the heavier nucleus.

Energy is released when nuclear fission reaction occurs

The energy equation is given as

Here we know that

= mass defect

mass defect is change in the mass of nuclei which occurs due to nuclei fission

so the correct reason for energy is given as

For large nuclei, the mass of the original nucleus is greater than the mass of the products.  

here mass of original nuclei is more than smaller nuclei because that mass will convert into energy which is released in the equation.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
