Alight year is the distance that ligth travels in a year.
Answer: C. The distance tat light travels in a year.
Mass=600kg
Velocity =15m/s
Momentum(p)=?
Now,
P=mass x velocity
=600x15
=9000kgm/s
Answer:
0.00461031264 m/s
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of the Earth = 6 × 10²⁴ kg
r = Distance between Earth and Sun = 
t = Time taken = 3 days
Acceleration is given by

Velocity of the star

The Sun's speed will be 0.00461031264 m/s
