In europe, gasoline efficiency is measured in km/l. if your car's gas mileage is 36.0mi/gal , how many liters of gasoline would you need to buy to complete a 142-km trip in europe? use the following conversions: 1km=0.6214mi and 1gal=3.78l.

atomic = no of protons.

mass number-atomic number = neutron number

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
