Given that the fragment a acquires three
times the kinetic energy of the fragment b.

Answer:
A. The bullet with 0.006kg has more energy
B. When the mass is doubled the kinetic energy increases
Explanation:
Kinetic energy increases when mass increases
kinetic energy increases when velocity increases
Answer: Infrasound is the span of low-frequency sounds below 20 Hz that fall below the hearing range of humans. While these sounds escape our ears, scientific instruments can detect them—and tell us some interesting things about the planet.
Explanation:
<u>Answer:</u> The correct answer is 2.24 MeV.
<u>Explanation:</u>
The chemical reaction for the formation of deuterium from proton and neutron follows:
We are given:
Mass of 
= 1.00784 u
Mass of 
= 1.008665 u
Mass of 
= 2.014102 u
To calculate the mass defect, we use the equation:
To calculate the energy released, we use the equation:
(Conversion factor: 
)
Hence, the energy released in the given nuclear reaction is 2.24 MeV.
