Water flows straight down from an open faucet. The cross-sectional area of the faucet is 2.00 10-4 m2, and the speed of the wate

r is 0.94 m/s as it leaves the faucet. Ignoring air resistance, find the cross-sectional area of the water stream at a point 0.11 m below the faucet.

Answer: 10.79×10^-5 m^2

Explanation:

v2 = 0.94m/s

Cross sectional area(A) = 2 × 10^-4m^2

v1A1 = v2A2 (continuity equation used to compare any two points of the flow of an incompressible fluid. )

A1 = (v2A2) ÷ v1

v1^2 = v2^2 + 2as

v1 = sqrt(v2^2 + 2as)

distance below faucet(s) = 0.11m

Acceleration during to gravity (a) = 9.8m/s^2

Substituting v1 into the continuity equation :

A1 = (v2A2) ÷ sqrt(v2^2 + 2as)

v2A2 = 0.94 × 2 × 10^-4m^2 = 1.88×10^-4

sqrt(0.94^2m/s + (2×9.8m/s^2×0.11m)) =

sqrt(0.8836 + 2.156) = 1.743

A1 = (1.88×10^-4)÷1.743

A1 = 0.000188 ÷ 1.743

A1 = 10.79×10^-5 m^2

The phrase "human rights" appears often in the news and in textbooks, but what exactly are human rights? Think about your own kn
ahrayia [7]

Answer:

Human rights are the basic rights and freedoms that belong to every person in the world, from birth until death.  They apply regardless of where you are from, what you believe or how you choose to live your life.

They can never be taken away, although they can sometimes be restricted – for example if a person breaks the law, or in the interests of national security. These basic rights are based on shared values like dignity, fairness, equality, respect and independence.  

How do human rights help you?

Human rights are relevant to all of us, not just those who face repression or mistreatment.

They protect you in many areas of your day-to-day life, including:

your right to have and express your own opinions

your right to an education  

your right to a private and family life

your right not to be mistreated or wrongly punished by the state

These values are defined and protected by law.

<em>The arrival of Modernism in the late 19th century lead to a radical break in the conception of the function of art,[117] and then again in the late 20th century with the advent of postmodernism. Clement Greenberg's 1960 article "Modernist Painting" defines modern art as "the use of characteristic methods of a discipline to criticize the discipline itself".[118] Greenberg originally applied this idea to the Abstract Expressionist movement and used it as a way to understand and justify flat (non-illusionistic) abstract painting: </em>
