Between June 21 and December 21, it moves from 23.5 north to 23.5 south ... 47 degrees of latitude.
Then during the other 6 months, it covers the 47 degrees to return back north.
But the rate at which it covers this range is not constant. The speed is "sinusoidal" ... slowest at
the ends, and fastest in the middle.
The first day of summer in the northern hemisphere is the day when the sun appears farthest north among the stars, at the point known as the "Summer solstice", usually on June 21 or 22. At that time, the sun is seen directly overhead from some point on the Tropic of Cancer ... the parallel of 23.5 degrees north latitude. It's never possible for the sun to be seen directly overhead anywhere in Texas. The southernmost point in Texas, near Brownsville, is about 170 miles north of the Tropic of Cancer.
Yes. Most places in the Hawaiian Islands will experience the noon Sun "straight overhead" twice each year. In fact, the phrase "Lahaina Noon" is sometimes used in the Islands to refer to those days on which the Sun reaches the zenith.
The French used direct rule to govern Vietnam.
The Tropic of Cancer ... an imaginary line of latitude in the Northern Hemisphere ... receives direct sun rays on June 21.
The tangent ray refers to either the northernmost or southernmost hemisphere where the vertical rays refers to direct sun. During the June 21 solstice, the latitude rays in the southern hemisphere would be 66.5 deg S (Antarctic Circle)
About 360o --- plus some small error due to Earth around Sun.
There's no place on Earth that always receives direct sunlight. The closest to it would be the Equator, where the sun goes from overhead to 23 degrees one way to overhead to 23 degrees the other way and back to overhead, in the course of a year. And you're right ... if latitude were the only component of climate, then the hottest would be all along the equator.
The Tropic of Cancer is located near this latitude, more specifically along 23°27' north latitude. This represents the northernmost points that can experience direct vertical insolation (Sun directly overhead) on at least one day of the year.
The specifics change depending on the latitude in question, but the noontime shadow will become shorter as the sun's direct rays of incidence approach the latitude in question and longer as the sun's direct rays of incidence recede from that latitude. For example, if you live at 45 degrees North, your shortest shadow will be on the summer solstice, since the sun's direct rays of incidence are at 23.5 degrees North on that day and will be south of that position on all other days. Conversely, if you live at the equator, your shortest shadows will be on the vernal and autumnal equinoxes, since the sun is directly overhead on those days.
The sun's rays are strongest at 0 degrees latitude.
From the Tropic of Cancer (23.45 degrees north) to the Tropic of Capricorn (23.45 degrees south).
Jun 21st is the summer solstice. The sun's latitude on that day is 23 1/2° and it would be directly overhead. This signals the first day of summer in the northern hemisphere and the first day of winter in the southern hemisphere.
Direct labor is not part of factory overhead while indirect labor is part of overhead as these labor expenses could not be calculated directly like factory supervisor salary or line manager salary etc.
Mileage is a overhead cost as mileage of cars or trucks which are not directly related with the manufacturing of units of products but required to transfer raw material from one place to another so it is overhead cost rather direct cost.
no direct cost is not an overhead
There is no time between these. On the day before the autumnal equinox, the sun is directly overhead in the northern hemisphere (at a latitude just north of the equator). The following day, it is directly overhead in the southern hemisphere (just south of the equator). The sun goes from being overhead in the northern hemisphere to the southern hemisphere instantaneously, the change happening at the autumnal equinox.
Prime cost includes direct material and direct labor without which no goods can be manufactured while production overhead is that other cost which is not directly identifiable with product but which is required to run factory operations.
