A student is probing a bacterium under the microscope. The E coli bacterial cell has a mass of = 1.80 (where a femtogram, is) and is swimming at a velocity of = 9.00 , with an improbability in the velocity of 4.00 . E. coli bacterial cells are around 1 ( ) in length. The student is assumed to observe the bacterium and make a drawing. but, the student, having just learned about the Heisenberg uncertainty principle in physics class, complains that she cannot make the drawing. She claims that the improbability of the bacterium's position is greater than the microscope's viewing field, as well as the bacterium is thus impossible to locate.
Explain what is the uncertainty of the position of the bacterium?
