Hi there!
II. Linear momentum of the system is zero. 
This is an example of a RECOIL collision. With the Law of Conservation of Momentum, momentum remains constant before and after the collision. 
Thus, the total momentum would also be equivalent to zero after the collision.
 
        
             
        
        
        
The relationship is directly proportional; as temperature increases, volume increases in the same way.
Charles's law states that at a constant pressure, the volume of fixed a mass of a gas is directly proportional to its absolute temperature or kelvin temperature.
Mathematically, this law can be written as follows;

This law explains the direct relationship between Volume of the gas and its Kelvin temperature. That is, as Temperature increases, the volume of the gas increases.
Thus, the correct statement is "The relationship is directly proportional; as temperature increases, volume increases in the same way".

The answer is letter C. <span>A train travels from the bottom of a hill to the top of a hill, its moves slower by the time it reaches the top is an example of negative acceleration.
In physics, acceleration can be described as an objects change of velocity. When an object gains velocity, it is positive acceleration, and negative acceleration for the opposite.
