In the apple-pulling-the orange sequence in this chapter, the force that accelerates the system across the floor is;
Friction between the apple and the floor.
<h3>Frictional Force</h3>
The sequence talked about here is a system showing how an apple was pulling an orange that was located inside a moving toy.
Now, we know that there is usually a force that acts between a moving object and the floor and this force is called friction force.
Thus, the force that makes the apple to pull the orange with acceleration across the floor is called friction force between the apple and the floor.

They will both hit the ground at the same time due to gravity.
that means they took the same time to travel the distance to the ground
however, the ball traveled farther
speed=distance (or displacement) divided by time
so the greater the distance, the greater the speed
the ball traveled faster in the same time so it traveled faster
answer is ball
<span>Radioactivity is the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei. Particles are emitted from the nuclei as a result of nuclear instability.

Answer:
1. A ruler is a common instrument used for measuring the length of small objects
2. The acceleration due to gravity at the surface of Earth is about 9.8 metres per second per second.
