The distance from Alexandria to Syene is about 500 miles. On the summer solstice the sun is directly overhead at noon in Syene.

svp [43]

Answer:

Earth circumference is 25000 miles

correct option is 25,000 miles

Explanation:

we have given here Alexandria to Syene distance = 500 miles

the sun is 1/50th of the circumference of the sky (about 7°)

as we know that Earth circumference done by astronomer Eratosthenes in 240 B.C

He observe on a particular time of day ( in noon) during the summer solstice

and there was no shadow in Syene in Egypt so This was verified that the sun must be directly on overhead and not at an angle to the surface of the city at that time

In Alexandria he measured the position of sun at the same time and found it to be nearly (1/50)th of a complete circle

it would be 7.2 degree (when we do $\frac{360}{50}$ = 7.2)

so 2 reference points being 2 cities for the sun

all measure circumference = the distance between these two cities × 50

and we have given 500 miles

Earth circumference = 500 × 50

Earth circumference is 25000 miles

correct option is 25,000 miles

Which statements reflect the point of view Senator Beveridge expresses in "March of the Flag”? Check all that apply.

viva [34]

Answer:

The correct answer would be ALL EXCEPT the colonization goes against the right to self-government and that expansion is too expensive. Senator Beveridge was one of those who believed that it was a destiny of the United States to become a superpower and that it should expand overseas. The colonization benefits the US and the US should colonize Philippines and free them from the yoke of other barbaric rules. The people of Philippines were also not able to govern themselves as are not children, nor the Native Americans as the senator believed that consent of the governed applies only to those who are able to govern themselves.
