A neutron star is moving in outer space at 4,000 km/hr. What happened to the star that set it in motion on it's current course?


a
the friction in space slowed it down to 4,000 km/hr
b
an unbalanced force from a supernova set it in motion
c
it was shot further into space due to the velocity of objects around it
d
a balanced force acted on it and propelled it to 4,000 km/hr

Respuesta :

Answer:

d

a balanced force acted on it and propelled it to 4,000 km/hr

Explanation:

For the neutrons star which is moving in outer space at 4,000 km/hr, it could only be possible as a result of the balanced force which had already acted on it. This is based on newton's law of motion which states that 'To every action, there is equal and opposite reaction'.
