Answer:
Perfectly inelastic collision 
Explanation:
There are two types of collision. 
1. Elastic collision : When the momentum of the system and the kinetic energy of the system is conserved, the collision is said to be elastic. For example, the collision of two atoms or molecules are considered to be elastic collision. 
2. Inelastic collision: When the momentum  the system is conserved but the kinetic energy is not conserved, the collision is said to be inelastic. For example, collision of a ball with the mud. 
For a perfectly elastic collision, the two bodies stick together after collision. 
Here, the meteorite collide with the Mars and buried inside it, the collision is said to be perfectly inelastic. here the kinetic energy of a body lost completely during the collision. 
 
        
             
        
        
        
Answer:
(a) 61.25 N 
(b) 6.25 kg
(c) 6.25 Kg
Explanation:
Weight on moon = 10 N 
Acceleration due to gravity on moon = 1.6 m/s^2 
Acceleration due to gravity on earth = 9.8 m/s^2 
Let m be the mass of the package.
(a) Weight on earth = mass x acceleration due to gravity on earth 
Weight on earth = 6.25 x 9.8 = 61.25 N
(b) Weight on moon = mass x acceleration due to gravity on moon
10 = m x 1.6 
m = 6.25 kg 
(c) Mass of the package remains same as mass does not change, so the mass of package on earth is 6.25 kg.
 
        
             
        
        
        
I do believe the answer is land because the ocean/sea gets cold when its night. So the answer is land
