Answer: Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field.
Answer:
![V=23.5L](https://tex.z-dn.net/?f=V%3D23.5L)
Explanation:
Hello,
In this case, it is convenient to compute the car's mileage in km/L as follows:
![25.0\frac{mi}{gal}*\frac{1km}{0.6214mi}*\frac{1gal}{3.78L}=10.64\frac{km}{L}](https://tex.z-dn.net/?f=25.0%5Cfrac%7Bmi%7D%7Bgal%7D%2A%5Cfrac%7B1km%7D%7B0.6214mi%7D%2A%5Cfrac%7B1gal%7D%7B3.78L%7D%3D10.64%5Cfrac%7Bkm%7D%7BL%7D)
In such a way, since the distance is measured to be 250 km, the volume requirement is:
![V=\frac{250km}{10.64kg/L}\\ \\V=23.5L](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B250km%7D%7B10.64kg%2FL%7D%5C%5C%20%5C%5CV%3D23.5L)

Answer: For Number #1)
The solution above is an acidic solution
Kw= {H+}*{OH^-}
[OH^-] =Kw/[H+]
OH^-= 1.0*10^14/ 1.0*10^-4
=1.0*10^4
Typical oxidation states of copper are
C u + l, and C U +I l cuprous and cupric ions.
