Answer:
The correct answer is<em><u> D. Set</u></em>
Explanation:
In contrast, <em><u>direct current</u></em> (DC) refers to a system in which the movement of electric charge in only one direction (sometimes called unidirectional flow). Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator -type electric machines of the dynamo type.
Answer:
three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. A divergent boundary occurs when two tectonic plates move away from each other.
Answer:

Explanation:
Angular momentum, L = m v r
areal velocity = 
according to kepler's 2nd law

since, we know that

areal velocity= 
now substituting value of v in areal velocity we get

hence from above equation of rate of change of area swept i.e. areal velocity is proportional to

Answer:
Weather is the day-to-day state of the atmosphere, and its short-term variation in minutes to weeks. People generally think of weather as the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind. ... Climate is the weather of a place averaged over a period of time, often 30 years.
As during the day earth heats from sun s short-range wavelength in night radiates out a long-wave from energy, as a result, the latitudes on the earth that are represented by the north and south line away from the equator experience uneven heating.
Air mass that have extremely cold and dry air is been classified as Arctic air mass. ... Equatorial air mass is warm and very moist and can be found in Equatorial region. Tropical air mass is warm and not humid and can be found in Mexico. Air mass plays an important role in controlling the weather significantly
