Question

7 of 7 Constants I Periodic Table A student is examining a bacterium under the microscope. The E. coll bacterial cell has a mass of m 1.40 fg (where a femtogram, fg, is 10 and is swimming at a velocity of t 8.00 m/s with an uncertainty in the velocity of 4.00 %. E. coli bacterial cells are around 1 jam (10 m) in length. The student is supposed to observe the bacterium and make a drawing. However, the student, having just learned about the Heisenberg uncertainty principle in physics class, complains that she cannot make the drawing. She claims that the uncertainty of the bacterlum's position is greater than the microscope's viewing field, and the- bacterium is thus impossible to locate. What is the unoertainty of the position of the bacterium? Express your answer with the appropriate units. View Available Hint(s) Ar 1.18x1010 m Previous Answers Correct Part B By looking at the uncertainty of the bacterium's position, did the student have a valid point? View Available Hint(s) The student has a point. The uncertainty of the bacterium's position is much larger than the bacterium itself The bacterium's size and the uncertainty of its position are about the same magnitude. The student should have little trouble finding the bacterium in the microscope The student is wrong. The uncertainty of the bacterium's position is tiny compared to the size of the bacterium itself Submit

Answer 1

Augwer: Part B : Size of bacterium= 10-bm uncertensity of bogthen of bacterium = 1.18 no tom It is clear that Size of bacterium > uncertainty in poginen 50; It is simply 104 timer meang Size of bacterium is lot times that of uncertaining so The student is wrong. The uncertensity of the bacterium's position is ting compared to the size of tue bacteriam.
