Explanation: According to this theory, an external event or stimulus causes a physiological change in the body but <em>at the same</em> <em>time</em> with an emotion, which is different from some other theories where emotions occur as a result of a physiological change due to an external event. As stated here, when Andrew heard the sharp crack of the twig he felt emotion, he froze with fear, and at the same time physiological change, a loud throbbing of the heart.
Answer:
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
But Earth's distance from the sun doesn't change enough to cause seasonal differences. Instead, our seasons change because Earth tilts on its axis, and the angle of tilt causes the Northern and Southern Hemispheres to trade places throughout the year in receiving the sun's light and warmth most directly
Relatively speaking, Earth's distance from the Sun doesn't change all that much throughout the year, nevertheless there are measurable differences in solar heating that result from our planet's slightly elliptical orbit.
Answer:
It is important that we recognize the Black mathematicians in history because it was due to their efforts that a lot of progress was made in the field of mathematics. History recognizes and appreciates the services of Benjamin Banneker who introduced the construction of a clock that struck every hour.
Dudley Weldon Woodard was an African- American who established the mathematics graduate program at Howard University.
