A mechanical wave is a disturbance in matter that transfers energy through the matter.
Mechanical waves require a medium to travel through, such as a solid, liquid, or gas.
Mechanical waves require a medium through which they can travel. The medium can be a solid, liquid, or gas. Examples of mechanical waves include water waves, sound waves, and seismic waves.

Potential energy or stored energy, and kinetic energy, the energy due to motion can be balanced in the process of converting kinetic energy to potential energy during an uphill motion
The correct option for, which situation shows potential energy and kinetic energy are balanced is option;
A roller coaster car going uphill
The reason the selected option is correct is as follows:
Potential energy is the energy that is due to the relative position of an item in relation to a ground or zero state. The formula for potential energy due to the elevation is given as follows;
Potential energy, P.E. = m·g·h
Kinetic energy is the energy that is due to motion. The kinetic energy of an item is given as follows;
Kinetic energy, K.E. = (1/2) × m × v²
The potential and kinetic energy of a body is balanced when we have;
P.E. = m·g·h = K.E. = (1/2)·m·v²
Which gives;
g·h = (1/2)·v²
Therefore, a point is reached as the an body moves up a heal, where the potential energy (the energy due to height of the object) and the kinetic energy (the energy due to current speed) of the object are equal
The correct situation which shows potential energy and kinetic energy are balanced is therefore; A roller coaster car going uphill

Answer :
1) Luster → the shininess of a material
2) Freezing point → temperature at which a liquid becomes a solid
3) Viscosity → the measure of a substance's resistance to flow
4) Solubility → ability to dissolve in another substance
5) Ductility → able to be pulled into a wire
Explanation :
Luster : It is defined as the material which has the shining property.
Freezing point : It is the temperature at which the phase changes from liquid state to solid state at low temperature.
Viscosity : It measures the resistance of the liquids to flow .
Solubility : It is defined as the ability of a substance (solute) to dissolve into a liquid (solvent).
Ductility : It is defined as the ability of a metal into a thin wire without breaking.
The physical properties are correctly matched as: Luster corresponds to the shininess of a material, freezing point is the temperature at which a liquid becomes solid, viscosity is the measure of a substance's resistance to flow, solubility is the ability to dissolve in another substance, and ductility refers to a substance's ability to be pulled into a wire
The correct matches for the physical properties and their descriptions are as follows:
It's crucial to understand these properties in chemistry, as they help us identify and characterize different substances.
