Answer: Two men who helped in the development of psychology in Germany was Wilhelm Wundt, and in United States was William James.
Explanation:
Wilhelm Wundt was a German scientist, who was the first person who introduced psychology. He studied the conscious experience as a part of scientific study. It emphasis the identification of the components of the consciousness. Introspection is the process through which conscious experiences can be analyzed.
William James was a scientist, native of U.S. His purpose was to study the function of behavior all over the world. This perspective was known as functionalism. This emphasizes over the fact that how mental activities helps how organisms fit into its surrounding environment.
Answer:
Explanation:
If there is a dielectric slab with thickness less than the distance between the plates is inserted inside a capacitor, then that capacitor can be regarded as two capacitors connected in series.
Let's assume that the slab is placed onto the lower side. So, the capacitance of that part of the capacitor, C1 is
where 
is the permittivity of the slab.
The other part of the capacitor is
Two capacitors are connected in series:
If we know the charge of the plates, we could relate the potential V0 to capacitance via
