Please answer this: Given the following passage "For example, at 30 MHz (10 m wavelength) a true resonant 14-wavelength monopole would be almost 2.5 meters long, and using an antenna only 1.5 meters tall would require the addition of a loading coil. Then it may be said that the coil has lengthened the antenna to achieve an electrical length of 2.5 meters. However, the resulting resistive impedance achieved will be quite a bit lower than the impedance of a resonant monopole, likely requiring further impedance matching. In addition to a lower radiation resistance, the reactance becomes higher as the antenna size is reduced, and the resonant circuit formed by the antenna and the tuning coil has a Q factor that rises and eventually causes the bandwidth of the antenna to be inadequate for the signal being transmitted. This is the major factor that sets the size of antennas at 1 MHz and lower frequencies.", answer the following question. Note that the answer is present within the text. Question: Why doesn't a coil work?
++++++++
Answer: the resulting resistive impedance achieved will be quite a bit lower than the impedance of a resonant monopole

Please answer this: Given the following passage "In astronomy, Al-Battani improved the measurements of Hipparchus, preserved in the translation of Ptolemy's He Megale Syntaxis (The great treatise) translated as Almagest. Al-Battani also improved the precision of the measurement of the precession of the Earth's axis. The corrections made to the geocentric model by al-Battani, Ibn al-Haytham, Averroes and the Maragha astronomers such as Nasir al-Din al-Tusi, Mo'ayyeduddin Urdi and Ibn al-Shatir are similar to Copernican heliocentric model. Heliocentric theories may have also been discussed by several other Muslim astronomers such as Ja'far ibn Muhammad Abu Ma'shar al-Balkhi, Abu-Rayhan Biruni, Abu Said al-Sijzi, Qutb al-Din al-Shirazi, and Najm al-Din al-Qazwini al-Katibi.", answer the following question. Note that the answer is present within the text. Question: __ served multiple terms as a judge in Seville and Cordoba

Answer: Averroes

Please answer this: Given the following passage "After having declined in size following the subjugation of the Mediterranean, the Roman navy underwent short-term upgrading and revitalisation in the late Republic to meet several new demands. Under Caesar, an invasion fleet was assembled in the English Channel to allow the invasion of Britannia; under Pompey, a large fleet was raised in the Mediterranean Sea to clear the sea of Cilician pirates. During the civil war that followed, as many as a thousand ships were either constructed or pressed into service from Greek cities.", answer the following question. Note that the answer is present within the text. Question: What kind of country were the romans from?
++++++++
Answer:
Republic
