While in Europe, if you drive 109 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 22.0 mi/gal ? Assume that 1euro=1.26dollars.

The amount is

Explanation:

From the question we are told that

     The  distance traveled per day is  

    The  cost of one liter is  

     The car's  gas mileage is  

Generally the amount of distance covered in one week is evaluated as

The  amount of gas used in one week by the car is mathematically represented as  

=>    

=>      

converting to liters

Thus the amount spent on gas in one week is  

=>      

=>      

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
