It consists of thirteen equal horizontal stripes of red (top and bottom) alternating with white, with a blue rectangle in the canton (referred to specifically as the ``union'') bearing fifty small, white, five-pointed stars arranged in nine offset horizontal rows, where rows of six stars (top and bottom) alternate with rows of five stars. The 50 stars on the flag represent the 50 states of the United States of America, and the 13 stripes represent the thirteen British colonies that declared independence from the Kingdom of Great Britain, and became the first states in the U.S. Nicknames for the flag include the Stars and Stripes, Old Glory, and the Star-Spangled Banner.
 Question: does each star on the flag represent a state Context: Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or Ftu within equations, is the capacity of a material or structure to withstand loads tending to elongate, as opposed to compressive strength, which withstands loads tending to reduce size. In other words, tensile strength resists tension (being pulled apart), whereas compressive strength resists compression (being pushed together). Ultimate tensile strength is measured by the maximum stress that a material can withstand while being stretched or pulled before breaking. In the study of strength of materials, tensile strength, compressive strength, and shear strength can be analyzed independently.
 Question: is tensile strength the same as breaking strength Context: The Helmand River flows through the mainly desert region of the province, providing water used for irrigation. The Kajaki Dam, which is one of Afghanistan's major reservoirs, is located in the Kajaki district. Helmand is believed to be one of the world's largest opium-producing regions, responsible for around 42% of the world's total production. This is believed to be more than the whole of Burma, which is the second largest producing nation after Afghanistan. The region also produces tobacco, sugar beets, cotton, sesame, wheat, mung beans, maize, nuts, sunflowers, onions, potato, tomato, cauliflower, peanut, apricot, grape, and melon.
