Answer 1

Answer:

C. 1.48x10–11 J

Explanation:

Answer 2

The energy which is required to split a nucleus into its discrete neutrons and protons is said to be nuclear binding energy.

Using the formula for nuclear binding energy:

E = Δmc²

where,

E = nuclear binding energy

Δm = mass defect

c = speed of light

Substitute the given value of mass defect and speed of light in above formula:

E = $1.643 \times 10^{-28} kg\times(3 \times 10^{8})^{2}m^{2}/s^{2}$

E = $14.787\times 10^{-12} kgm^{2}/s^{2}$

$kgm^{2}/s^{2}$ = Joule.

E= $1.48\times 10^{-11} J$

Thus, nuclear binding energy of an atom is $1.48\times 10^{-11} J$.
