I don't exactly know the answer but maybe the explination will help
Explanation:
As planters increased cotton production, they rapidly increased the purchase and transport of slaves. By 1840 there were 11,323 slaves in Texas.
Answer:
He orders the bins in the store-shed to be filled with sand, hidden beneath a layer of grain and meal, and then shows them to Mr. Whymper.
Explanation: He wanted to fool him into thinking that the farm has plenty of food.
Answer:
The Euphrates is the longest and one of the most historically important rivers of Western Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia.
Explanation:
The Euphrates is important solely for its water supply. The river is the source of political tension, as Turkey, Syria and Iraq all compete for the use of its waters for irrigation and the generation of hydroelectric power. For centuries the river formed the east limit of Roman control. “There is no water!” The Euphrates is drying up. Strangled by the water policies of Iraq's neighbors, Turkey and Syria; a two-year drought; and years of misuse by Iraq and its farmers, the river is significantly smaller than it was just a few years ago. Some officials worry that it could soon be half of what it is now.

From Keplers discovery, scientists were also able to infer that the closer a satellite is to an object, the stronger the force of attraction, hence it must travel faster in order to maintain orbit. Relying on this formula, we are able to see that the velocity required for orbit is equal to the square root of the distance from the object to the center of the Earth times the acceleration due to gravity at that distance. So if we wanted to put a satellite in a circular orbit at 500 km above the surface (what scientists would call a Low Earth Orbit LEO), it would need a speed of ((6.67 x 10-11 * 6.0 x 1024)/(6900000))1/2 or 7615.77 m/s. So really, a satellites ability to maintain its orbit comes down to a balance between two factors: its velocity (or the speed at which it would travel in a straight line), and the gravitational pull between the satellite and the planet it orbits. If youd like more info on satellites, check out these articles: Orbital Objects List of satellites in geostationary orbit Weve also recorded an episode of Astronomy Cast about the space shuttle.
