Answer:
A
Explanation:
option A is correct
the best example of elastic collision among the following is collision between two billiard balls. In collision of two billiard balls the energy lost is very little approximately zero. hence we can say that the kinetic energy is conserved. since, the kinetic energy is conserved we can say that the collision is elastic
Yes, this was a good choice
Hope that helped,

If the two cups are the same/equal in all regards the spoon makes the difference in heat loss. Metal spoon is a good conductor, heat conducts up the spoon handle. Radiant and convection losses occur in the surrounding air. Metal becomes a “heat sink”.
Spoon will feel warmer to the touch than a pottery or foam cup that is not a good conductor.
As per conditions described here we know that all force arrow are not of equal length
So all forces are not same in magnitude
Here applied force on right direction is more in magnitude then the friction force on left
So it will have net unbalanced force towards right due to which it will move towards right direction or in the direction of net unbalanced force
While in the upward and downward direction the forces are balanced and hence the box will not move in that direction
So normal force will be balanced by gravitational force
So here answer will be
The forces acting on the box are <u>UNBALANCED</u> .
The box will move to the <u>RIGHT</u> .
It is the thermal energy transferred from a hot object to a cool object.
The following statement listed above is correct.
Answer: True.
