A neutron star's immense gravitational attraction is due primarily to its small radius and A neutron star's immense gravitationa
1 answer:
Answer:
Large mass.
Explanation:
A neutron star is one whose whole mass is concentrated in a small space. Thus, a neutron star has a very large mass and and a small radius. We know that Gravitational force
That is F is directly proportional to mass and inversely proportional square of radius. Therefore, a neutron star has an immense gravitational attraction

Answer:
The acceleration is about 9.8 m/s2 (down) when the ball is falling.
Explanation:
The ball at maximum height has velocity zero
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.8 m/s² (positive downward and negative upward)
The accleration 9.8 m/s² will always be acting on the body in opposite direction when the body is going up and in the same direction when the body is going down. The acceleration on the body will never be zero
