Answer:
The correct answer is from solid to liquid (melting), and from liquid to gas (sublimation).
Explanation:
In the solid-state the energy of the molecules is low, so the molecules will have very little movement. In the liquid state, molecules have a higher level of energy, and as they move from solid to liquid state they acquire greater mobility. In a gaseous state, the energy level is very high and the molecules have a higher degree of mobility.
This can also be described through the predominant molecular forces in each state. The cohesion forces present in solids are stronger than those of repulsion. In the liquid state, the repulsion and attraction forces are balanced. Finally, in the gaseous state, the repulsive forces between the molecules predominate.

Sedimentary Rocks are made from previously existing rock.
Answer:
B) both the amplitude of the motion and the weight of the ball
Explanation:
Time period of a pendulum is given by
where,
L = Length of pendulum
g = Acceleration due to gravity
The system here is similar to a simple pendulum
It can be seen that the time period depends on L and g.
Amplitude and weight are the factors that do not determine the time period.
Hence, the answer is B) both the amplitude of the motion and the weight of the ball
