Does changing the eccentricity change the semi major axis?
Does changing the eccentricity change the semi major axis? An ellipse has an eccentricity in the range 0 < e < 1, while a circle is the special case e=0. Elliptical orbits with increasing eccentricity from e=0 (a circle) to e=0.95. For a fixed value of the semi-major axis, as the eccentricity increases, both the […]

What happens after refraction when 4 a A ray of light parallel to principal axis passes through a concave lens?
What happens after refraction when 4 a A ray of light parallel to principal axis passes through a concave lens? One ray of light becomes parallel to the principal axis of the lens and thus, passes through another focus after refraction through the lens. Another ray of light passes through the optical centre of the […]
Can you tell your ethnicity by facial features?
Can you tell your ethnicity by facial features? Ancestry and physical appearance are highly related; it is often possible to infer an individual’s recent ancestry based on physically observable features such as facial structure and skin color. Which parent determines facial features? However, according to new research, the nose is the part of the face […]
What Three criteria are used to evaluate a theory?
What Three criteria are used to evaluate a theory? Fawcett’s criteria are significance, internal consistency, parsimony, testability, empirical adequacy, and pragmatic adequacy. Some of those criteria are differentiated for grand theories and middle-range theories but are not differentiated by type of data-qualitative or quantitative-used to develop the theory. What are the basic components of theory? […]

Why do the edges of shadows seem blurry?
Why do the edges of shadows seem blurry? The blurry edges of everyday shadows are caused by the light sources being extended objects. Light from different parts of the source are able to travel into the shadow area because they emanate from different points in space. The darker, inner part of the shadow where no […]
