Answer:

73,483,200 W/m^2

Explanation:

BY the stefan Boltzman law the energy radiated by a body is propotional to fourth power of its absolute temperature. Sun is considered to be black body,hence ts emisivity is one.

E= σT^4

σ= Boltsman constant = 5.67×10^(-8)

putting values we get

E= 5.67\times10^{-8}\times6000^4

= 73,483,200 W/m^2

energy emitted by the sun = 73,483,200 W/m^2

How can new technologies in geography help us to answer geography’s three key questions?
svp [43]

Geography's relevance to science and society arises from a distinctive and integrating set of perspectives through which geographers view the world around them. This chapter conveys a sense of what is meant by a geographic perspective, whether it be applied in research, teaching, or practice. Due to space limitations, it does not attempt to cite the many excellent examples of research illustrating geography's perspectives; the citations refer mainly to broad-ranging summaries of geographic research that are intended as resources for further reading.

Taking time to understand geography's perspectives is important because geography can be difficult to place within the family of academic disciplines. Just as all phenomena exist in time and thus have a history, they also exist in space and have a geography. Geography and history are therefore central to understanding our world and have been identified as core subjects in American education. Clearly, this kind of focus tends to cut across the boundaries of other natural and social science disciplines. Consequently, geography is sometimes viewed by those unfamiliar with the discipline as a collection of disparate specialties with no central core or coherence.

How does flooding rice fields reduce the need for herbicides and pesticides in rice farming? a. while rice has a submerged growt
Talja [164]

The Correct Answer : <u>Flooding the fields causes the soil to degrade so weeds cannot take root.</u>

Rice has a submerged growth state while most weeds do not. Therefore, flooding rice fields reduces the growth of these less robust pests without negatively affecting the rice crop. Flooding the fields also deters many kinds of vermin that would otherwise live in the soil and harm the rice plants because they cannot breathe underwater.

<u />

<h3>What is Pesticides?</h3>

Pesticides are chemicals that may be used to kill fungus, bacteria, insects, plant diseases, snails, slugs, or weeds among others. These chemicals can work by ingestion or by touch and death may occur immediately or over a long period of time.

<h3>What is Herbicides?</h3>

Herbicides are used to kill undesirable plants or “weeds”. Some herbicides will kill all the plants they touch, while others are designed to target one species.

<u />

Therefore, we can conclude that the correct option is B.
