Here is a question about this article: For horizontal propagation between transmitting and receiving antennas situated near the ground reasonably far from each other, the distances traveled by tne direct and reflected rays are nearly the same. There is almost no relative phase shift. If the emission is polarized vertically, the two fields (direct and reflected) add and there is maximum of received signal. If the signal is polarized horizontally, the two signals subtract and the received signal is largely cancelled. The vertical plane radiation patterns are shown in the image at right. With vertical polarization there is always a maximum for θ=0, horizontal propagation (left pattern). For horizontal polarization, there is cancellation at that angle. Note that the above formulae and these plots assume the ground as a perfect conductor. These plots of the radiation pattern correspond to a distance between the antenna and its image of 2.5λ. As the antenna height is increased, the number of lobes increases as well.
What is the answer to this question: When is the emission at maximized recieved signal?
****
So... polarized vertically


Here is a question about this article: Nicholas began courting Britain by means of conversations with the British ambassador, George Hamilton Seymour, in January and February 1853.:105 Nicholas insisted that he no longer wished to expand Imperial Russia:105 but that he had an obligation to the Christian communities in the Ottoman Empire.:105  The Tsar next dispatched a highly abrasive diplomat, Prince Menshikov, on a special mission to the Ottoman Sublime Porte in February 1853. By previous treaties, the sultan was committed "to protect the (Eastern Orthodox) Christian religion and its churches." Menshikov demanded a Russian protectorate over all 12 million Orthodox Christians in the Empire, with control of the Orthodox Church's hierarchy. A compromise was reached regarding Orthodox access to the Holy Land, but the Sultan, strongly supported by the British ambassador, rejected the more sweeping demands.
What is the answer to this question: Who wanted to ruled over the 12 million Orthodox Christians in the Empire?
****
So... Menshikov


Here is a question about this article: Bell's patent 174,465, was issued to Bell on March 7, 1876, by the U.S. Patent Office. Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically ... by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound" [N 16] Bell returned to Boston the same day and the next day resumed work, drawing in his notebook a diagram similar to that in Gray's patent caveat.
What is the answer to this question: On what day did Bell go back to Boston?
****
So...
March 7, 1876
