Answer:C The final velocity is half of trained car B's initial velocity.
Explanation:
According to the Law of conservation of momentum, the total momentum of the system before and after the collision remains same. The momentum may transfer from one object to another as a result of the impact, but the overall momentum of the system remains same.
So, the correct answer is option a.
The total initial momentum of all objects interacting with one another usually equals the total final momentum.
Answer:
Factors determining the state of substances
* Inter molecular force : substances having strong intermolecular force will be solid and substance with weak inter molecular force will be gas.
* Nature of chemical bond:
Ionic compounds are generally solid in nature because of strong intermolecular force.
Polar covalent compounds may be solid or liquid
Non polar covalent compounds generally gas
* Electro negativity difference: greater the electronegativity difference, greater will be the intermolecular force.

Answer:
Explanation:
Lithification is the process by which sediments compact under the influence of pressure and the sediments become rocks. This process limits the porosity by destruction of porosity by compaction and cementation.
Sandstone is clastic sedimentary rock that forms by the process of lthification which involves the compaction and cementation of sand grains.
