Answer:
The particle model of matter is one of the most useful scientific models because it describes matter in all three states. Understanding how the particles of matter behave is vital if we hope to understand science!
The model also helps us to understand what happens to the particles when matter changes from one state to another.
The following diagram shows different changes of state, as well as which processes are the reverse of each other. Melting and freezing are the reverse processes of each other and so are evaporation (boiling) and condensation.
Explanation:
To develop this problem it is necessary to apply the concepts related to destructive interaction.
By definition we know that it is given as
Where,
l = Distance between slits
m = Any integer representing the number of repetition of spectrum
There is a change in phase at the upper side of the film which causes the phase shift since the index of refraction of the soap film is greater than that of air.
The extra traveled distance is twice the film thickness since the light shines perpendicularly and the wave travels back and fourth through the film, so
(second smalles nonzero thickness) we have that
The index of refraction of soap is given so the relationship is
Substituting the previos equation
Re, arrange to find \lambda_{vacuum}
Therefore the vacuum wavelength of the light is 575.89nm
Answer:
The water takes longer, because it is the better insulator here.
Explanation:
Conductors and insulators work similarly in "reverse".
If something is a good heat conductor, then it's good at both absorbing heat energy and giving it away. Insulators are good at resisting temperature changes, but also take longer to cool down once they are heated up.
So because copper is the better conductor here, it will cool faster than the water at the same temperature.
Answer:
Diabetic Retinopathy is a form of diabetes that affects the eyes. It can be caused by damage to the retinas, and can cause permanent damage to the eyes, and even blindness. Initially the patient is asymptomatic and become more visibly affected in later stages. It can be treated if caught early, or in mild cases.
