An Excited U^* Nucleus Undergoes Fission into Two Fragments,as

question 5

Multiple Choice

An excited U^* nucleus undergoes fission into two fragments,as shown: U^* → Ba + Kr The following atomic masses are known: Kr: 91.926270 u Ba: 143.922845 u U^*: 236.045563 u
Assume,at a given instant,that the two fission fragments are spherical,just barely in contact,and carry spherically symmetric charge distributions.At that instant,what is the electrostatic interaction energy of the two fragments,in MeV? (1 u = 1.6605 × 10^-27 kg = 9

• A) 230 MeV
• B) 240 MeV
• C) 250 MeV
• D) 260 MeV
• E) 270 MeV

Definitions:

T Score

A type of standardized score that has been adjusted to fit a normal distribution, typically with a mean of 50 and a standard deviation of 10.

Test-Retest Reliability

The consistency of a psychological test or assessment over time, measured by administering the same test to the same subjects at two different points in time.

Standard Error of Measurement (SEM)

A statistic that reflects the amount of error in the measurement of a score, indicating its accuracy and precision.
