A typical car driven 20,000 km a year emits to the atmosphere about 11 kg peryear of NOx(nitrogen oxides), which cause smog in major population areas. Natural gas burned in the furnace emits about 4.3 g of NOxper therm (1 therm= 105,500 kJ), and the electric power plants emit about 7.1 g of NOxper kWhof electricity produced. Consider a household that has two cars and consumes9000kWh of electricity and 1200 therms of natural gas per year. Determine theamount of NOxemission to the atmosphere per year for which this householdis responsible.

explanation:

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

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
