In 2019, the International Committee for Weights and Measures adopted a new set of definitions for the fundamentalunits of the SI system. The three important base units in classical mechanics are the unit of time (s), the unit of length(m), and the unit of mass (kg). These three units are derived from three physical constants in the new SI system:QuantitySymbol UnitsTransition Frequency of Cesium 133 Avs-1kg - m?/sm/sPlanck's ConstanthSpeed of LightUse dimensional analysis to determine the combination of these three parameters that will define the base units ofthe SI system.(a) What combination of h, c, and Av defines a second?(b) What combination of h, c, and Av defines a meter?(c) What combination of h, c, and Av defines a kilogram?You only need to find the combination of h, c, and Av that has the right units. Your answer should not involve anynumerical values.

A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of m = 0.300 fg (where a femtogram, fg, is 10−15g) and is swimming at a velocity of v = 9.00 μm/s , with an uncertainty in the velocity of 6.00 % . E. coli bacterial cells are around 1 μm ( 10−6 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 bacterium's position is greater than the microscope's viewing field, and the bacterium is thus impossible to locate. What is the uncertainty of the position of the bacterium? Express your answer with the appropriate units (m).
