A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae.
Answer:
Option c is correct
Explanation:
There are two types of collisions-elastic collision and inelastic collision.
In elastic collision, both kinetic energy and total momentum are conserved. On the other hand, in inelastic collision, total momentum is conserved but kinetic energy is not conserved. Thus, option b and d are incorrect.
Total energy is always conserved in both types. Thus, option a is incorrect.
In a perfectly inelastic collision, objects stick together. This happens because maximum kinetic energy is dissipated and used in bonding of the two objects. Thus, correct option is c.
It's C i believe. To solve it we just take 20 and divide it by 2. Which gives us the average of 10 m/s

Answer:
Weight of the fluid that the object displaces.
Explanation:
When the fluid is completely immersed in a fluid, it experiences pressure from all the direction. While the object is immersed in the fluid a force acts on it in the opposite direction, i.e., upwards. This force is termed as buoyant force.
Also, as per the Archimedes' Principle, the force experience by the object is the same as the weight of the fluid that gets displaced by the object.
Thus on complete immersion of the object in the fluid, it experiences the force same as the weight of the fluid that gets displaced
