Reason why the international dateline is significant

1 answer:

5 0

The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852.

The International Date Line functions as a “line of demarcation” separating two consecutive calendar dates. When you cross the date line, you become a time traveler of sorts! Cross to the west and it’s one day later; cross back and you’ve “gone back in time."

Which type of seismic waves are confined at the surface?

AfilCa [17]

The types of seismic waves are confined at the surface are

Rayleigh waves
Love waves

<u>Explanation:</u>

Rayleigh wave are having the motion of retrograde particle which is confined to the vertical plane of the motion. Love wave are having the motion which is transverse which is confined to horizontal plane of the motion. If we talk about other mentioned waves than P waves, S- waves all travel in different pace from slow to fastest. S-waves travel in slow pace whereas p-waves are called the fastest. Disperse waves also travel in a decent speed

6. The original length, L, and original width, W. of a rectangular garden are BOTH increased by 3 feet each.

ASHA 777 [7]

Answer:

Explanation:

A rectangle is a two-dimensional quadrilateral.

The area is given as:

Area of a rectangle = length x width

Perimeter = 2(L+ W)

where L is the length and W is the width

Condition:

If L and W are increased by 3 feet each;

New length = L + 3

New width = W + 3

Area of new rectangle;

Area = (L + 3) x (W + 3)

= LW + 3L + 3W + 9

Perimeter of new rectangle;

Perimeter = 2(L+3 + W + 3)

= 2(L+W +6)

Answer:

Because Mexico–U.S. migration represents the largest sustained migratory flow between two nations worldwide, much of the theoretical and empirical work on migration in the Americas has focused on this single case. Yet in the past few decades, migration has emerged as a critical issue across all nations in Latin America and the Caribbean. Indeed, over the past fifteen years, this region has changed its historical position from a net migrant-receiving region to one of the leading sending areas of the world.

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
