While in europe, if you drive 121 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 26.0 mi/gal ? assume that 1euro=1.26dollars .

The cost of gas for week will $104.89.

Explanation:

Distance traveled in one day = 121 km =75.17 mile

(1 km = 0.6313 mile)

Distance traveled in a week i.e. in 7 days =75.17 × 7= 526.19 miles

Mileage of the car = 26 miles/gal

Gas used for travelling 1 mile = gal/mil

Gas used in travelling 526.19 mile :

Cost of 1 liter of gas = €1.10

1 gal = 3.785 L

So, 19.995 gal =

Cost of 75.6810 L gas = €1.10 × 75.6810=€83.2491

€ 1 = $ 1.26

Cost in dollars = $83.2491 × 1.26 = $ 104.89

The cost of gas for week will $104.89.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
