makkiz [27]
The energy of the electron reduces as it moves closers to the nucleus. This is because it moves from a higher energy orbital to a one of lower energy. It does this by releasing a photon with the energy difference of the current energy level, and the energy level it drops too.

In Europe, gasoline efficiency is measured in km/L. If your car’s gas mileage is 25.0 mi/gal, how many liters of gasoline would
Deffense [45]

Answer:

V=23.5L

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}

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

Regards.
