Answer: Government passing regulatory laws
Car emissions testing
Carpooling and less driving overall
Air pollution results when a mixture of particles and gases that can reach in harmful concentrations both outdoors as well as indoors. This increase in concentration can lead to rise in the temperatures and global warming it is also related with the health hazards. Soot, smoke, pollen, carbon dioxide, carbon monoxide and methane are the examples of the common pollutants.
Government passing regulatory laws: The government can ban some of the fossil fuels to prevent air pollution, and some vehicles which are likely to emit more partially combustible gases.
Car emission testing: Nowadays, cars and other vehicles are equipped with catalytic converters which converts the uncombustible gaseous products into less harmful gases which are emitted from the vehicle. The car gas emission testing should be performed to either allow a vehicle or ban the movement of the vehicle.
Carpooling and less driving overall: Carpooling is the sharing of one vehicle with more than one individual. This will prevent the need of others to drive another vehicle. The less the number of vehicles on the road the lesser will be the emission of gases and less pollution will be caused.
Answer:
9.03 x 10³ m /s
Explanation:
magnetic field inside a solenoid
B = μ₀ n I , where μ₀ = 4π X 10⁻⁷ .
n is no of turns per unit length and I is current
so B₁ = 4π x10⁻⁷x 593 / 20.9 x 5.65 x 10²
201.5 x 10⁻⁴ T
B₂ = 4π x 10⁻⁷ x 343 / 19.1 x 1.37 x 10²
= 30.93 x 10⁻⁴ T
Net magnetc field
B₁ -B₂ = B = (201.5 - 30.93) x 10⁻⁴ T
B = 170.57 x 10⁻⁴ T
Now protons move in circular path of radius R in the magnetic field of B
B q v = m v² / R
v = B q R / m
= 170 .57 x 10⁻⁴ x 1.6 x 10⁻¹⁹ x 5.53 x 10⁻³ / (1.67 x 10⁻²⁷)
= 903.71 x 10
= 9.03 x 10³ m /s

The statement that best describes the production of energy in the Sun is nuclei with less mass combine to form nuclei with more mass in the Sun’s core and release energy.
<h3>How is energy produced in the sun?</h3>
Sun is a major source of renewable energy to the Earth. This energy serves various purposes by living organisms.
However, the energy is generated as a result of nuclear fusion, which is the combination of smaller particles to form a larger one.
Therefore, the statement that best describes the production of energy in the Sun is nuclei with less mass combine to form nuclei with more mass in the Sun’s core and release energy.
