The diagram illustrates the evolution of the universe, starting from the big bang. Each concentric circle represents a stage in the evolution as
stated by the big bang theory. The arrows illustrate the changes that happened after the big bang and leading up to the stage where gases
were formed that later led to the formation of stars and galaxies. Choose the inaccurate statements on the diagram.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

kg • m/s.

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
