Good designs offer users as many alternatives as possible a. True b. False

1 answer:

3 0

The answer to is
b. False

Good designs or more specifically, good designers should prepare multiple design choices that users can choose from. People have different tastes and sense of style. A designer should not impose his own preference and provide different perspectives for the users.<span />

Softa [21]

In my opinion, venturing into world of Arts could be a favorable path for a person highly interested in solitary, introverted work. Visual arts such as painting and photography (nature, macro-shoots, etc) could be better choices. Literature might interest you too. The art of words would allow you to express yourself without talking to animate objects. One could pick a pen or stare at his or her computer when indulging oneself in the ARTS.

You do not have to impress others, your masterpiece could do the talking for you.

Hope this helps. Have a nice day!

National accounting identities Let C stand for consumption spending, I for investment, G for government purchases, X for exports

madreJ [45]

Answer:

A. National income must equal domestic product.

True.

Explanation:

National Income is the total value of goods and services produced in a country during a financial period. It is total income from a country's economic activities.

Domestic product is monetary value of all economic activities of a country during a period.

National Income is sum of Investments, Savings, Government expenditures and net exports. National Income equals the domestic products of a country. The equation is as follows:

C + I + G + (X - IM) = DI + NT.

The statement given is true. Disposable income equals the saving plus consumption. The excess of disposable income which is not consumed is saved. Sum of saving and consumption must equal Disposable income in an economy.

A body in the solar system has a period of 10,759.22 days and a perihelion speed of 10.18 km/s. a. Calculate the aphelion radius

anastassius [24]

Answer:

Explanation:

From the information given, by applying Kepler's 3rd law,

$T^2 \alpha a^3$

where;

T = period

a = semi major axis

T = 356 days (for earth)

a = 1 AU = 1.496 $\times 10^8 \ km$

Therefore, $T^2 = ca^3$

$c= \dfrac{365^2}{(1.496 \times 10^8)^3}$

c = 3.9791 $\times 10^{20} \ day^2/km^3$

However, if the body in the solar system has a period of 10.759.22 days, then, a =?

∴

$T^2 = ca^3$

$a3 = \dfrac{10759.22^2}{3.9791 \times 10^{-20}}$

$a^3 = 2.9092 \times 10^{27}$

$a= \sqrt[3]{2.9092 \times 10^{27}}$

a = 1.4275 $\times 10^9 \ km$

However, the velocity for a perihelion = 10.18 km/s

Using the formula

$v = \sqrt{GM ( \dfrac{2}{r}-\dfrac{1}{a})}$ to calculate the radius, we have:

G = $6.674 \times 10^{-11}$

M = $1.989\times 10^{30} \ kg$

r = perihelion

$v ^2= GM ( \dfrac{2}{r}-\dfrac{1}{a})$

$(10.18 \times 10^3) ^2= 6.674 \times 10^{-11} \times 1.989 \times 10^{30} ( \dfrac{2}{r}-\dfrac{1}{1.425 \times 10^{12}})$

$7.8068 \times 10^{-13}= \dfrac{2}{r}-\dfrac{1}{1.425 \times 10^{12}}$

$\dfrac{2}{r} = 1.4824 \times 10^{-12}$

$r = \dfrac{2}{1.4824 \times 10^{-12}}$

$r = 1.349 \times 10^{12}$

Similarly, the perihelion is expressed by the equation,

r = a(1 - e)

where ;

e= eccentricity

∴

$1.349 \times 10^{12} = 1.425 \times 10^{12} ( 1 - e)$

$1.349 \times 10^{12} - 1.425 \times 10^{12}= - 1.425 \times 10^{12} (e)$

$-7.6\times 10^{10}= - 1.425 \times 10^{12} (e)$

$\dfrac{-7.6\times 10^{10}}{- 1.425 \times 10^{12}}= (e)$

e ( eccentricity) = 0.0533

Aphelion radius in natural miles, r = a( 1+ e)

$r = 1.425 \times 10^{12} ( 1 + 0.0533)$

$r = 1.50 \times 10^{12} \ m$

to nautical miles, we have:

$r = 1.50 \times 10^{12} \times 0.00054 \ nautical \ mile$

radius of aphelion $\mathbf{r = 8.10 \times 10^8}$ nautical miles

In respect to the value of a( i.e $1.4275 \times 10^9 \ km)$

the body of the solar system is Saturn
