While in europe, if you drive 125 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 40.0 mi/gal ? assume that 1euro=1.26dollars.

You would spend $71.32 per week on gas.

Step 1. Convert weeks to days

Time = 1 wk × (7 days/1 wk) = 7 days

Step 2. Calculate the distance travelled

Distance = 7days × 125 km/day = 875 km

Step 3. Convert kilometres to miles

Distance = 875 km × (1 mi/1.609 km) = 543.8 mi

Step 4. Calculate the gallons of gas

V = 543.8 mi × (1 gal/40.0 mi) = 13.60 gal

Step 5. Convert gallons to litres

V = 13.60 US gal × (3.785 L/1 US gal) = 51.46 L

Step 6. Calculate the cost of the gas

Cost = 51.46 L × (€1.10/1 L) = €56.60

Step 7. Convert euros to dollars

Cost = €56.60 × ($1.26/€1) = $71.32

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.
