What could be the average human density? Justify?

Answers

Answer:

985 kg/m3

Explanation:

The average density of the human body is 985 kg/m3 k g / m 3 , and the typical density of seawater is about 1020 kg/m3 k g / m 3 .

Explanation:

the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2 (38 per sq. mi.). If only the Earth's land area of 150,000,000 km2 (58,000,000 sq. mi.) is taken into account, then human population density is 50 per km2 (129 per sq.

Dos resistencias de 30 y 20 Ω se conectan en seria a un generador que tiene una diferencia de potencial de 20 V entre sus bornes. a. Determina la resistencia equivalente de la asociación b. Dibuja el circuito y coloca un amperímetro que indique el valor de la intensidad de la corriente y unos voltímetros que muestren la diferencia de potencial entre los extremos de las resistencias ¿Qué valores muestran estos aparatos?

Answers

Answer:

   V = 12V,  V = 8V

Explanation:

a) In this series circuit the equivalent resistance is

          Req - R1 + R2

          Req = 30 + 20

          Eeq = 50 Ω

b) see attached

c) the circuit current is

          i = V / Req

          i = 20/50

          i = 0.4 A

voltages are>

         V = 0.4 30

          V = 12V

           V = 0.4 20

            V = 8V

According to ohms law, as the voltage increases across a 40 ohm resistor what happens to the current, resistors, and resistance

Answers

Answer:

As the voltage increases, the current flowing through the circuit increases while the resistance of the resistor remains constant.

Explanation:

Ohm's law states that the current flowing through a circuit is directly proportional to the applied voltage.

V = IR

where;

I is the current

R is the resistance

V is the applied voltage

Based on this law (Ohm's law), as the voltage increases, the current flowing through the circuit increases while the resistance of the resistor remains constant.

The tallest Ferris wheel in the world is located in Singapore. Standing 42 stories high and holding as many as 780 passengers, the Ferris wheel has a diameter of 150m and takes approximately 30 minutes to make a full circle. Determine the speed of the riders (in m/s) on the Singapore Flyer.

Answers

Answer:

The speed of the riders on the Singapore Flyer is approximately 0.262 m/s

Explanation:

The dimensions of the tallest Ferris wheel in the world are;

The diameter of the Ferris wheel, D = 150 m

The tine it takes the Ferris wheel to make a full circle, T = 30 minutes = 30 min × 60 s/min = 1,800 seconds

The angular velocity of the Ferris wheel, ω = 2·π/T

The linear velocity of the Ferris wheel, v = r·ω = The speed of the riders

Where;

r = The radius of the Ferris wheel = D/2

D = 150 m

∴ r = 150 m/2 = 75 m

∴ v = r·2·π/T

∴ v = 75 m × 2 × π/(1,800 s) ≈ 0.262 m/s

The speed of the riders on the Singapore Flyer, v ≈ 0.262 m/s

with well labelled diagrams , describe how a bicycle pump works​

Answers

Explanation:

this is almost similar to how a syringe works. when the pump is drown out, air in the barrel expands and pressure is reduced to below atmospheric pressure. the air from outside the pump is at high pressure so it flows past the leather washer into the barrel. at some point, the higher pressure in the tyre closes for valve.

when the pump handle is pushed in the air is forced into the tyre though the tyre valve which now opens

Craft a strong thesis that fully responds to the prompt. Write full body paragraphs (6-10 sentences) that contain direct quotes and commentary that develops and expands your argument about the rhetorical choices and message of the author.The following passage is excerpted from the 1990 newspaper article America Needs Its Nerds by Leonid Fridman. At the time of the articles publication, Fridman was a graduate student at Harvard University and a member of Harvards Society of Nerds and Geeks. Read the passage carefully. Write an essay that analyzes the rhetorical choices Fridman makes to develop his argument.In your response you should do the following:Respond to the prompt with a thesis that analyzes the writers rhetorical choices.Select and use evidence to support your line of reasoning.Explain how the evidence supports your line of reasoning.Demonstrate an understanding of the rhetorical situation.Use appropriate grammar and punctuation in communicating your argument.There is something very wrong with the system of values in a society that has only derogatory terms like nerd and geek for the intellectually curious and academically serious.A geek, according to Websters New World Dictionary, is a street performer who shocks the public by biting off heads of live chickens. It is a telling fact about our language and our culture that someone dedicated to pursuit of knowledge is compared to a freak biting the head off a live chicken.Even at a prestigious academic institution like Harvard, anti-intellectualism is rampant: Many students are ashamed to admit, even to their friends, how much they study. Although most students try to keep up their grades, there is a minority of undergraduates for whom pursuing knowledge is the top priority during their years at Harvard. Nerds are ostracized while athletes are idolized.The same thing happens in U.S. elementary and high schools. Children who prefer to read books rather than play football, prefer to build model airplanes rather than get wasted at parties with their classmates, become social outcasts. Ostracized for their intelligence and refusal to conform to societys anti-intellectual values, many are deprived of a chance to learn adequate social skills and acquire good communication tools.Enough is enough.Nerds and geeks must stop being ashamed of who they are. It is high time to face the persecutors who haunt the bright kid with thick glasses from kindergarten to the grave. For Americas sake, the anti-intellectual values that pervade our society must be fought.There are very few countries in the world where anti-intellectualism runs as high in popular culture as it does in the U.S. In most industrialized nations, not least of all our economic rivals in East Asia, a kid who studies hard is lauded and held up as an example to other students.In many parts of the world, university professorships are the most prestigious and materially rewarding positions. But not in America, where average professional ballplayers are much more respected and better paid than faculty members of the best universities.How can a country where typical parents are ashamed of their daughter studying mathematics instead of going dancing, or of their son reading Weber* while his friends play baseball, be expected to compete in the technology race with Japan or remain a leading political and cultural force in Europe?
