WebMar 31, 2024 · Bismuth is a chemical element with symbol Bi and atomic number 83. However, in 2003 it was discovered to be extremely weakly radioactive: its only primordial isotope, bismuth-209, decays via alpha decay with a half-life more than a billion times the estimated age of the universe. WebVerified answer. engineering. In order to move a wrecked truck, two cables are attached at A A and pulled by winches B B and C C as shown. Knowing that the tension is 10 \mathrm {kN} 10kN in cable A B AB and 7.5 \mathrm {kN} 7.5kN in cable A C AC, determine the magnitude and direction of the resultant of the forces exerted at A by the two cables.
