the first vector is 27° with a force of 23 N. The second vector us 75° with a force of 30 N. Use 10 N = 1 cm as your scale. What is the resulting vectort The first vector is 224° with a force of 27 N. The second vector is 123°, with a force of 32 N. What is the resulting vector? In example C the first vector is 80° with a force of 16 N. The second vector is 144° with a force of 48 N. What is the force and degrees of the resulting vector?

In 1995 a research group led by eric cornell and carl wiemann at the university of colorado successfully cooled rubidium atoms to the 20-200 nk temperature range. assuming (incorrectly) that the rubidium atoms behave liké particles of a classical ideal gas, calculate the rms speed of a rubidium atom at a temperature of 112.0 nk. in the experiments one particular isotope of rubidium was used, rubidium-87. the molar mass of this isotope is 86.91 q/mol. tries 0/20 submit answer
