When 235U Undergoes Fission, the Average Energy Per Fission Event $200 \mathrm { MeV }$

question 24

Multiple Choice

When 235U undergoes fission, the average energy per fission event is $200 \mathrm { MeV }$ . How much energy is released in the total fission of $2.0 \mathrm {~g}$ of $235 \mathrm { U }$ ? $\left( 1 \mathrm { eV } = 1.60 \times 10 ^ { - 19 } \mathrm {~J} , m _ { \text {neutron } } \approx m _ { \text {proton } } = 1.67 \times \right.$ 10-27 kg)

• A) \(3.9 \times 10 ^ { 10 } \mathrm {~J}\)
• B) \(1.6 \times 10 ^ { 11 } \mathrm {~J}\)
• C) \(1.6 \times 10 ^ { 5 } \mathrm {~J}\)
• D) \(3.9 \times 10 ^ { 13 } \mathrm {~J}\)

Terrestrial plants are species that grow on land rather than in water, adapting to a variety of habitats from forests to deserts.

Aquifer

Rock layers that contain water and release it in appreciable quantities to wells or springs.

Rate Of Recharge

The speed at which an aquifer or a rechargeable battery regains its capacity or is refilled after use.

Groundwater Mining

The process of extracting water from underground aquifers at a rate faster than the natural recharge, leading to depletion or diminishing of groundwater resources.
