Answer:
The EMF of each battery is 6 volts and the EMF of two batteries connected in series is 12 volts.
Explanation:
According to the Kirchhoff's Voltage Law, net voltage of a closed circuit must be zero. That is:
(1)
Where 
is the voltage of the i-th component of the closed circuit, measured in volts. Please notice that voltage for a power generating element (i.e. EMF) is less than zero and for a power consuming element is greater than zero (i.e. Batteries being charged by the EMF). In addition, if n-elements are connected in series, then the equivalent voltage is:
(2)
Let consider that closed system is formed by two batteries connected in series and an EMF, by (1) and (2) we have that:
(3)
If we know that 
, then the EMF of the battery is:
The EMF of each battery is 6 volts and the EMF of two batteries connected in series is 12 volts.
The term "erosion" best describes how soil and rock pieces travel from one location to another.
Erosion in earth science refers to the activity of surface processes, such as wind or water currents, that shift rock, soil, or dissolved material from one area in the Earth's crust to another. The dynamic action of erosive elements including ice, water, snow, plants, wind, animals, and people causes this natural phenomenon.
Earthen materials are worn away during erosion, a geological process in which they are moved by wind or water. Water, ice, acids, salts, plants, animals, and temperature changes are some of the weathering agents. Erosion is the process by which the broken pieces of rock and mineral are carried away after a rock has been fractured.

Answer:
The composition of Earth's core Solid iron surrounded by molten iron .
Explanation:
Earth's Core -
Earth's core is the hottest and the deepest layer in the Earth . It is composed of two layers , first is , the outer core , which is type of border between the mantle and the core , and second is the inner core .
The inner core is rich in solid , and mainly contains iron , and the outer core is in liquid state , which is rich in nickel and iron metals . the outer core is where the Earth gets its magnetic field .
