Explanation:
The five basic postulate of kinetic molecular theory includes:
1) All gases consist of large amount and numbers of tiny particles that are far apart from each other and also relative to their size.
2) The collisions between gas particles and gas particles against container walls is refer to as elastic collision.
3) All gas particles are in a continuous random and rapid motion. They possess kinetic energy which is energy of motion.
4) There are no attractive force between gas particles.
5) The temperature of a gas depends on the average kinetic energy of the gas particle.

Answer:
2.1844 m/s
Explanation:
The principle of conservation of momentum can be applied here.
when two objects interact, the total momentum remains the same provided no external forces are acting.
Consider the whole system , gun and bullet. as an isolated system, so the net momentum is constant. In particular before firing the gun, the net momentum is zero. The conservation of momentum,
assume the bullet goes to right side and the gravitational acceleration =10 
so now the weight of the rifle=
this is a negative velocity to the right side. that means the rifle recoils to the left side
Hello there!
Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
