Question

If the nuclear fission piece of uranium of mass 5.0 g is lost, the energy obtained in kWh is?

• A. \(1.25 \times 10^7 \)
• B. \(2.25 \times 10^7 \)
• C. \(3.25 \times 10^7 \)
• D. \(0.25 \times 10^7 \)

Hint:

Nuclear fission releases a large amount of energy as a result of mass loss.

Answer 1

The Correct Option is A

The energy released from nuclear fission can be calculated using the formula: \[ E = mc^2 \] Where \( m \) is the mass and \( c \) is the speed of light. Given the mass of uranium and the corresponding energy released, we can compute the energy in kWh.
