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).

calculate the slope and uncertainty in the slope

If you have a simple pendulum where the equation of its linear graph is : L = g(T/2pi)2 where x = (T/2pi)2 and Y = L (where L is the length of the pendulum in m) and b=0. How will you calculate the uncertainty of X and Y? ??= ? ??= ?

A bird flies a distance of d- 150+3 m during a time 20.0+1.0 s The average speed of the bird is u-d/t = 7.5 m/s. what is the uncertainty of u? Question 2. Suppose that we're able to eliminate the uncertainty in our time mea- surement so that t = 20.0 ±0.0 s. What is the new uncertainty of u?

The first screenshot displays the question, and the second screenshot displays the section of the book that's relevant to the problem. So far, there have been two incorrect answers given:  a.) 2.82 x e^-(1.51 x 10^12), and  b.) (1.60*10^-19)^-(2.04*10^11) If someone can solve this problem, it would be deeply appreciated!

(answer using 6 significant digits) What is the absolute uncertainty of the density of vibranium with a mass of 186.000 ± 0.004 g and a volume of 120.00 ± 0.02 mL?(answer with two significant digits)

A toy duck is floating on the water. The average density of the duck is ρd = 760 kg/m3, while the density of water is ρ = 1.0 x 103 kg/m3. The volume of the duck is Vd = 0.00011 m3.Randomized Variables ρd = 760 kg/m3Vd = 0.00011 m3 a) Express the weight of the duck, W, in terms of ρd and Vd.  b)Calculate the numerical value of W in Newtons.  c) Express the magnitude of the buoyant force, F, in terms of ρ and the volume of water that the duck displaces, Vw.

The radius of circle has been measured as r = (4.19 ± 0.3) cm. Calculate the uncertainty δA (in cm²) of its area (A = πr²). Enter the number only, without unit.

surface, denoted by “g”. In this imaginary experiment, you have measured g three times. The values you obtain are:                 g1 = 10.2 meters per second squared  (m/s2)                 g2 = 10.4 m/s2                 g3 = 10.0 m/s2   To find the Average Value of g, denoted by gav, simple add up the experimental values and divide by the number of experimental values you have:                              g1 + g2  + g3         10.2 + 10.4 + 10                  gav  =  __________  = ____________  =   10.2 m/s2 .                                   3                           3                                  Percent Error (PE)   To find the Percent Error (PE), you compare the average experimental value to the standard or handbook value of the physical quantity you are measuring. The Standard Value of gravitational acceleration at Earth’s surface , gst, is 9.8 m/s2.         Mathematically, PE is defined as:                                           (Average - Standard)…
