Answer:

Explanation:
Given data:
exhaust velocity = 2.455 km/s
specific impulse = 294 second


Ve = effective exhaust velocity

Isp specific impulse
g_o = standard gravity

from above equation we have
[ 2.455 km/s = 2455 m/s]

Answer:
Two important examples of isolated languages are:
Basque: Basque is spoken by around 750,000 people in the Spanish Autonomous Community of Basque Country, and in the French department of Pyrenees-Atlantiques.
Basque is so isolated that it is a pre-Indo European language, and has survived over the years because the Basque Country is very mountainous, and because the Basque people have gone great leaps to protect it.
Korean: spoken by about 77 million people in both North Korea and South Korea, Korean is actually an isolated language because it does not have any close relations with any other language, or language family.
It has survived because Korea has been an important East Asian civilization since over one thousand years ago, and the prospect of this language is more positive than ever because of the increasing economic and cultural power of South Korea.
It is a lot like the Northern states with having snow every year, but they are different because most of Northern Canada is in the Arctic Circle.
Considering the available options, the term that describes airflow from west to east is known as <u>Zonal Flow.</u>
<h3>What is Zonal Flow?</h3>
Zonal Flow is a term used to describe wind or airflow from the west-east direction.
The Zonal Flow can also flow along the Latitudinal lines or latitudinal circles.
Zonal flow is a term commonly used in atmospheric and geographical sciences, and it brings a temperature contrast along the Earth's longitude.
Hence, in this case, it is concluded that the correct answer is option A. "<u>Zonal Flow."</u>

Answer: 
Explanation:
We can divide this figure in a rectangle with base
and height
; and a right triangle with base
and height
.
Now, the total area
of the figure will be the area of the rectangle
plus the area of the triangle
:

Where:


Then:

This is the area of the figure
