Answer: They have different rigidities.
Explanation:
Answer:
B
Explanation:
Because vector Y is longer than vector X
so when you take a magnitude( without minus ) each other
you see that Y>X
Answer:

3257806.62409 m/s
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of Sun = 
r = Radius of Star = 20 km
u = Initial velocity = 0
v = Final velocity
s = Displacement = 16 m
a = Acceleration
Gravitational acceleration is given by

The gravitational acceleration at the surface of such a star is 

The velocity of the object would be 3257806.62409 m/s
