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.

Answer:
Another issue that the Appalachians faced was inflation. Inflation caused many issues surrounding families, and when things got too tough, families would flee and leave. McKinney states, “For essential goods, prices increased rapidly, placing them beyond the reach of many families.
Explanation:
If the temperatures are increasing in a mountainous region, in order to be sure in that, the evidence can simply be obtained by the vegetation. The mountains tend to be warmer at the lower parts, and as the elevation increases, the temperature decreases. If it is a higher mountain, then we will see that there is certain type of vegetation in the lower parts, above it a belt of another vegetation type, above that one there's usually a belt of grasses, and the highest parts are usually with little to no vegetation. If the temperature increases though, then the vegetation from the bottom will start moving upwards, occupying larger portion, the second layer will move upwards as well, and the grasses will come around the top part of the mountain, with the barren part disappearing from the scene.
Hi there,
I hope you and your family are staying safe and healthy!
