a deuterium (an isotope of hydrogen) nucleus (mass = 2.01355 amu) is made
up of one proton (mass = 1.007276 amu) and one neutron (mass = 1.008665
amu). which statement best describes what happens when a deuterium
nucleus forms?
o
a. energy is conserved, but mass is not.
o
b. energy is converted into mass.
o
c. mass is converted into energy.
o
d. mass is conserved, but energy is not

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.

explanation:

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
