Problem: The actual antenna which is transmitting the original wave then also may receive a strong signal from its own image from the ground. This will induce an additional current in the antenna element, changing the current at the feedpoint for a given feedpoint voltage. Thus the antenna's impedance, given by the ratio of feedpoint voltage to current, is altered due to the antenna's proximity to the ground. This can be quite a significant effect when the antenna is within a wavelength or two of the ground. But as the antenna height is increased, the reduced power of the reflected wave (due to the inverse square law) allows the antenna to approach its asymptotic feedpoint impedance given by theory. At lower heights, the effect on the antenna's impedance is very sensitive to the exact distance from the ground, as this affects the phase of the reflected wave relative to the currents in the antenna. Changing the antenna's height by a quarter wavelength, then changes the phase of the reflection by 180°, with a completely different effect on the antenna's impedance.
what happens to the reflected wave which allows the antenna to reach its asympotic feedpoint impedance?
The answer is the following: reduced power


The company, which benefited from the imperial patronage, soon expanded its commercial trading operations, eclipsing the Portuguese Estado da Índia, which had established bases in Goa, Chittagong, and Bombay, which Portugal later ceded to England as part of the dowry of Catherine de Braganza. The East India Company also launched a joint attack with the Dutch United East India Company on Portuguese and Spanish ships off the coast of China, which helped secure their ports in China. The company established trading posts in Surat (1619), Madras (1639), Bombay (1668), and Calcutta (1690). By 1647, the company had 23 factories, each under the command of a factor or master merchant and governor if so chosen, and 90 employees in India. The major factories became the walled forts of Fort William in Bengal, Fort St George in Madras, and Bombay Castle.
how many employees were in the factories in India?
90


Input: LaserDisc
In the mid-1980s Lucasfilm pioneered the EditDroid non-linear editing system for film and television based on computer-controlled LaserDisc players. Instead of printing dailies out on film, processed negatives from the day's shoot would be sent to a mastering plant to be assembled from their 10-minute camera elements into 20-minute film segments. These were then mastered onto single-sided blank LaserDiscs, just as a DVD would be burnt at home today, allowing for much easier selection and preparation of an Edit Decision List. In the days before video assist was available in cinematography, this was the only other way a film crew could see their work. The EDL went to the negative cutter who then cut the camera negative accordingly and assembled the finished film. Only 24 EditDroid systems were ever built, even though the ideas and technology are still in use today. Later EditDroid experiments borrowed from hard-drive technology of having multiple discs on the same spindle and added numerous playback heads and numerous electronics to the basic jukebox design so that any point on each of the discs would be accessible within seconds. This eliminated the need for racks and racks of industrial LaserDisc players since EditDroid discs were only single-sided.

How many EditDroid systems were ever built?
Output: 24


Input: Article: Literature consists of written productions, often restricted to those deemed to have artistic or intellectual value. Its Latin root literatura/litteratura (derived itself from littera, letter or handwriting) was used to refer to all written accounts, but intertwined with the roman concept of cultura: learning or cultivation. Literature often uses language differently than ordinary language (see literariness). Literature can be classified according to whether it is fiction or non-fiction and whether it is poetry or prose; it can be further distinguished according to major forms such as the novel, short story or drama; and works are often categorised according to historical periods or their adherence to certain aesthetic features or expectations (genre).

Now answer this question: What two key elements that distinguish literature as a written form of art?

Output: deemed to have artistic or intellectual value


Article: Public policy and political leadership helps to "level the playing field" and drive the wider acceptance of renewable energy technologies. Countries such as Germany, Denmark, and Spain have led the way in implementing innovative policies which has driven most of the growth over the past decade. As of 2014, Germany has a commitment to the "Energiewende" transition to a sustainable energy economy, and Denmark has a commitment to 100% renewable energy by 2050. There are now 144 countries with renewable energy policy targets.

Question: What drives the wider acceptance of renewable energy technologies?
Ans: Public policy and political leadership


Input: Buddhism
Gautama was now determined to complete his spiritual quest. At the age of 35, he famously sat in meditation under a Ficus religiosa tree now called the Bodhi Tree in the town of Bodh Gaya and vowed not to rise before achieving enlightenment. After many days, he finally destroyed the fetters of his mind, thereby liberating himself from the cycle of suffering and rebirth, and arose as a fully enlightened being (Skt. samyaksaṃbuddha). Soon thereafter, he attracted a band of followers and instituted a monastic order. Now, as the Buddha, he spent the rest of his life teaching the path of awakening he had discovered, traveling throughout the northeastern part of the Indian subcontinent, and died at the age of 80 (483 BCE) in Kushinagar, India. The south branch of the original fig tree available only in Anuradhapura Sri Lanka is known as Jaya Sri Maha Bodhi.

What kind of tree was the Bodhi Tree?
Output:
Ficus religiosa
