If the star Alpha Centauri were moved to a distance 10 times farther than it is now, its parallax angle would ______
Virty [35]

Answer: get smaller

Explanation:

Parallax is the angle formed by the observation lines to a very distant object from two separated points.

The procedure to measure this distance in the case of a star, is based on observing it from two different places far away from each other, and then through trigonometry reach to the following relationship:

d=\frac{r}{sin \theta} (1)

Where:

d is the distance from Earth to the observed star (in Parsecs 1pc=206265AU)

r is the earth-sun distance that is equivalent to an astronomical unit (1AU=150000000km)

\theta is the angle of the parallax (in arc seconds '')

Now, the distance to an object (measured in parsecs) is the reciprocal of the parallax (measured in arcseconds).  Then, in its simplified mode, the stellar parallax is given by the following equation:

d=\frac{1}{\theta} (2)

As we can see, there is an inverse relation between the distance d and the parallax \theta:

\theta=\frac{1}{d} (3)

Hence, if the distance is increased by a factor of 10, the parallax is decreased by a factor of 10.

In other words, the  parallax angle gets smaller.

In 1798 Thomas Malthus argued that populations grew exponentially while food supplies grew arithmetically. Consequently, Malthus
Alik [6]

Answer:

Malthus theory was wrong because he did not take into account that food supply could also grow exponentially, thanks to advances in technology such as mechanization (for example, tractors), the use of pesticides and fertilizers, and the development of agricultural science.

He also did not predict that population growth would eventually taper down, at least in the developed world, because urbanization, industrialization, and the rise of living standards have shown to result in families with fewer children.
