Mr. Mullenmeister is photocopying lab sheets for his first-period class when the toner light on the onA particle of toner carrying a charge of the copying machine experiences an electric field of 1.2 * 10 ^ 6 * N / C as it's pulled toward the paper. What is the electric force acting on the toner particle? F=4.5=(40*10^ C)(1.2*106N/C)=4.8*10^ .5

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
