d. Schmidt focus
A change in momentum
Newton's Third Law
The conservation of Momentum
B. Main sequence
C. Nebula
D. Protostar
The correct answer is D. Protostar.
Nuclear fusion in a star's lifecycle begins during the protostar stage. This is when the temperature and pressure of the protostar ignite nuclear fusion, transitioning into a main sequence star.
In the life cycle of a star, nuclear fusion begins when the star has reached the protostar stage. The initial stage in the development of a star is the nebula, which is a cloud of dust and gas. Over time, the nebula's materials collapse under gravity to form a hot core known as a protostar.
When the protostar's temperature and pressure rises, it triggers nuclear fusion and the star begins turning hydrogen into helium.
This marks the transition from a protostar to a main sequence star, which is the stage of stable nuclear fusion.
