Answer:
The true statement is that different gases with the same mass and temperature always have the same average kinetic energy. This is one of the postulates of the kinetic theory of matter.
If we two objects A and B, they will have mass mA and mB and velocity vA and vB respectively. If K.E = 1/2mv^2 . Then it follows that
1/2mAvA = 1/2mBvB. Since the mass is the same it means the velocity of the two objects should be the same so that they have the same average kinetic energy.
I think the answer is B. Geographers use different kinds of maps, depending on the subject they are studying. <span />
Boston, the biggest burg in New England, is located on a mountainous peninsula in Massachusetts Bay. The region had been inhabited since at least 2400 B.C. by the Massachusetts race of Native Americans, who assemble the peninsula Shawmut. Fearing more tension between Native Americans and settlers, England's King George III upshot the Proclamation of 1763, prohibiting residence westward of the Allegheny Mountains.
Highwall mining is often used when excavating an open-pit mine becomes too expensive. There are many advantages over underground mining, including the fact that it is both more cost-effective and involves less lead time.
Prevailing winds are the planetary winds that are caused by the formation of giant convection cells over the earth. Prevailing winds blow from the hot regions of the earth, like the tropics, to the cold areas of the earth, like the temperate or polar regions, and from the cold areas back to the hotter regions.
