The radiation pattern of an antenna is a plot of the relative field strength of the radio waves emitted by the antenna at different angles. It is typically represented by a three-dimensional graph, or polar plots of the horizontal and vertical cross sections. The pattern of an ideal isotropic antenna, which radiates equally in all directions, would look like a sphere. Many nondirectional antennas, such as monopoles and dipoles, emit equal power in all horizontal directions, with the power dropping off at higher and lower angles; this is called an omnidirectional pattern and when plotted looks like a torus or donut.
A plot of the radiation behaviors of an antenna would show what?
A: relative field strength

Much civil-defence preparation in the form of shelters was left in the hands of local authorities, and many areas such as Birmingham, Coventry, Belfast and the East End of London did not have enough shelters. The Phoney War, however, and the unexpected delay of civilian bombing permitted the shelter programme to finish in June 1940.:35 The programme favoured backyard Anderson shelters and small brick surface shelters; many of the latter were soon abandoned in 1940 as unsafe. In addition, authorities expected that the raids would be brief and during the day. Few predicted that attacks by night would force Londoners to sleep in shelters.
What civil-defense efforts were left to local authorities to handle?
A: shelters

This does not mean that samurai women were always powerless. Powerful women both wisely and unwisely wielded power at various occasions. After Ashikaga Yoshimasa, 8th shogun of the Muromachi shogunate, lost interest in politics, his wife Hino Tomiko largely ruled in his place. Nene, wife of Toyotomi Hideyoshi, was known to overrule her husband's decisions at times and Yodo-dono, his concubine, became the de facto master of Osaka castle and the Toyotomi clan after Hideyoshi's death. Tachibana Ginchiyo was chosen to lead the Tachibana clan after her father's death. Chiyo, wife of Yamauchi Kazutoyo, has long been considered the ideal samurai wife. According to legend, she made her kimono out of a quilted patchwork of bits of old cloth and saved pennies to buy her husband a magnificent horse, on which he rode to many victories. The fact that Chiyo (though she is better known as "Wife of Yamauchi Kazutoyo") is held in such high esteem for her economic sense is illuminating in the light of the fact that she never produced an heir and the Yamauchi clan was succeeded by Kazutoyo's younger brother. The source of power for women may have been that samurai left their finances to their wives.
Who was Ashikaga Yoshimasa?
A: 8th shogun of the Muromachi shogunate

The primary law is that players other than goalkeepers may not deliberately handle the ball with their hands or arms during play, though they do use their hands during a throw-in restart. Although players usually use their feet to move the ball around, they may use any part of their body (notably, "heading" with the forehead) other than their hands or arms. Within normal play, all players are free to play the ball in any direction and move throughout the pitch, though the ball cannot be received in an offside position.
What type of position can a ball always be received in?
A:
unanswerable
