Pluto has a shape that is nearly round, and it orbits the Sun. It has five known moons. It is called a dwarf planet and not a planet because its orbit is not cleared of like-sized or larger objects

Answer: Option B

<u>Explanation:</u>

According to the International Astronomical Union (IAU), Pluto has been mentioned as Dwarf Planet as it doesn't hold the standardisation to be counted as a Planet.

According to the standard criteria, a planet must have been surrounded by the orbit of the Sun, it must have significant mass to have a gravitational pull and hence, circular shape, and should have isolated surrounding.

But, Pluto has various celestial bodies in its vicinity that are larger in size. Hence, as concluded by the Union, any celestial body that does not has clear surrounding, is regarded as Dwarf Planet just like Pluto.

Which of the following is a form of pollution created when vehicle exhaust interacts with sunlight?
SVEN [57.7K]

Photochemical smog is formed when primary air pollutants interact with sunlight.

Photochemical smog is the result of the reaction between pollutants like  nitrogen oxides (NO), sunlight and volatile organic compound (VOC) in the atmosphere. The sources of NO are car exhaust, coal power plants, factory emissions, etc. This type of smog is also known by the name Los Angeles smog.

Air pollutants are the particles present dissolved in the air, which when inhaled by the organisms can cause serious health issues. These pollutants are :ozone, particulate matter, gaseous oxides, etc. These pollutants majorly affect the respiratory system of the humans.

Therefore, photochemical smog is a form of pollution created when vehicle exhaust interacts with sunlight.

In the following diagram, the voltage is 1.5 volts and the resistance is 0.35 ohms. Use Ohm's Law to determine the current in th
Angelina_Jolie [31]

Answer:

I = 4.28 [amp]

Explanation:

To solve this type of problems we must have knowledge of the law of ohm, which tells us that the voltage is equal to the product of resistance by current.

Initial data:

v = 1.5 [volt]

R = 0.35 [ohms]

v = I * R

therefore:

I = 1.5 / 0.35

I = 4.28 [amp]
