Answer:
The price of a floating currency is determined by the currency exchange market while the price of a fixed currency is connected to the price of some other commodity.
From lakes and grasslands with hippos and giraffes to a vast desert, North Africa's sudden geographical transformation 5,000 years ago was one of the planet's most dramatic climate shifts.
The transformation took place nearly simultaneously across the continent's northern half, a new study finds. The results will appear in an upcoming issue of the journal Earth and Planetary Science Letters.

Answer:
The Erie Canal is a 363-mile waterway that connects the Great Lakes with the Atlantic Ocean via the Hudson River in upstate New York. The channel, which traverses New York state from Albany to Buffalo on Lake Erie, was considered an engineering marvel when it first opened in 1825. The Erie Canal provided a direct water route from New York City to the Midwest, triggering large-scale commercial and agricultural development—as well as immigration—to the sparsely populated frontiers of western New York, Ohio, Indiana, Michigan and points farther west. The canal transformed New York City into the young nation’s economic powerhouse, and in 2000 the U.S. Congress designated the Erie Canal a National Heritage Corridor.
Explanation:
I do my history a lot .
Answer:
A. Element Name: Flourine
no. of electrons (e^-)=Atomic number (Z)=no. of protons (p^+)
no. of neutrons (n^0)=Atomic mass-no. of protons (p^+) i.e. (n^0)=10
B. Element Name: Neon
Atomic mass=no. of electrons/protons + no. of neutrons i.e. 10+10=20
no. of protons (p^+)=no. of electrons (e^-)=Atomic number (Z)=10
Charge= -2
Explanation:
Charge is the tendency of an atom to lose or gain an electron. The gaining of electron is a positive charge (+) and the losing of an electron is a negative charge (-).
