If the waves are sound waves, the change in frequency is heard as a change in pitch. As a sound source moves toward the listener, the waves reach the listener with a higher frequency. The pitch appears to increase because of the Doppler effect. ... It describe the quality of the sound you hear.

Answer:
.
Explanation:
F = kx so k = 800/((10-5)/100) = 16000 N/m
W = 1/2 kx^2 = 1/2 * 16000 * .05^2 = 20 J.
(sorry if it's wrong)
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.
