An aircraft is climbing at a 30 degree angle to the horizontal. How fast is the aircraft gaining altitude if it's speed is 500 m

denis-greek [22]

Answer:

The aircraft is gaining altitude at $250\frac{mi}{h}$

Explanation:

Draw a vector diagram. (Right angle triangle speed as the hypotenuse)

Let

x -----> horizontal component of the speed

y ----> vertical component of the speed

s ----> speed in miles per hour

we know that

$x=cos(30\°)(s)$

$y=sin(30\°)(s)$

we have

$s=500\ \frac{mi}{h}$

$cos(30\°)=\frac{\sqrt{3}}{2}$

$sin(30\°)=\frac{1}{2}$

substitute

$x=\frac{\sqrt{3}}{2}(500)$

$x=250\sqrt{3}\frac{mi}{h}$

$y=\frac{1}{2}(500)$

$y=250\frac{mi}{h}$

therefore

The aircraft is gaining altitude at $250\frac{mi}{h}$

The mass of the Sun is 2 × 1030 kg, and the distance between Neptune and the Sun is 30 AU. What is the orbital period of Neptune

Volgvan

<h2>Orbital Period:</h2>

To answer this problem, we must employ the gravitational notion and equation. We already know that gravitational force provides the required centripetal force for orbital motion. As a result of matching gravitational and centripetal forces, we may get the equation for orbital time period.

<h2>Answer and Explanation:</h2><h3>Given:</h3>

Mass of Sun (M) = 1.99 * 10^30 Kg
Orbital radius of the Neptune
(R) = 30 A.U. = 30 * (1.496 * 10^11) m
R = 44.88 * 10^11 m

Now we know that the time period is given by

T^2 = 4π^2R^3/GM

T^2 = 4π^2*(44.88*10^11)^3/6.67*10^-11*(1.99*10^30)

T = 5.19 * 10^9 s

Now we know that

1 year = 3.154 * 10^7 s

Therefore, T = 5.19*10^9 s/ 3.154 * 10^7 (s/year)

T = 164.4 year

Define sociology of culture can you write 4 paragraph

iogann1982 [59]

The sociology of culture, and the related cultural sociology, concerns the systematic analysis of culture, usually understood as the ensemble of symbolic codes used by a member of a society, as it is manifested in the society.

Among sociologists, “culture” just as often refers to the beliefs that people hold about reality, the norms that guide their behavior, the values that orient their moral commitments, or the symbols through which these beliefs, norms, and values are communicated.

Culture encompasses human elements beyond biology: for example, our norms and values, the stories we tell, learned or acquired behaviors, religious beliefs, art and fashion, and so on.

Sociology of culture is important because culture influences people's beliefs and behaviors, culture is a key concept to the sociological perspective. Many sociologists are wary of biological explanations of behavior, in part because these explanations implicitly support the status quo and may be used to justify claims of biological inferiority.
