Question

Use error propagation to find the uncertainty in T as a function of T and delta T. What is the equation for error propagation?

Answer #1

Propagation of error: Determine the uncertainty in the
concentration if you dissolved 0.500 ± 0.001 g of NaCl in the
average glass pipet volume determined above. Use the SD of the
volume and propagation of error rules to perform this calculation.
Report the concentration and uncertainty both in terms of Molarity
and ppm for Na+
Average is 24.9 mL and SD is 0.030
I get 0.34 +/- 0.002 for molarity but I don't know how to solve
for ppm, Please...

The general equation for calculating the mean is: . Apply the
propagation of error to calculate the error of this mean and
simplify it for when all errors for xiare the
same.

1) Find the uncertainty in kinetic energy. Kinetic energy
depends on mass and velocity according to this function E(m,v) =
1/2 m v2. Your measured mass and velocity have the
following uncertainties 0.01 kg
and 0.37 m/s. What is is the uncertainty in
energy, , if the measured mass, m = 0.68 kg and the
measured velocity, v = 1.09 m/s? Units are not needed in your
answer
2) The propagation of uncertainty formula for the equation y =
ax^2 is
where ,and ....

Error Propagation:
Experiment was to find the dimensions of a table. We were given
50 sets of values.
From those values, I found the mean and standard deviation.
Dimensions., cm
Mean Value, cm
Standard Deviation, cm
Error (stand. dev. of mean), cm
Width
75.94
1.096
0.0219
Length
182.2
1.184
0.0237
What I need:
1. Error or standard deviation of the mean for both
length and width. Which is the equation: standard
deviation/50.
For width I got 0.0219 cm
Length is...

Use the moment generating function Mx(t) to find the mean u and
variance o^2. Do not find the infinite series.
Mx(t) = e^[5*((e^t)-1)]

3. (10 pts) Heisenberg Uncertainty Principle
The uncertainty principle places a limit on specifying the
location and momentum of a particle simultaneously. Δ?Δ? ≥ ℏ/2 This
is a consequence of the wave nature of particles, which we can see
by examining the uncertainty in the single-slit diffraction of
light.
(a) In single-slit diffraction, the width of the slit ?
represents the uncertainty in x position of the beam, ∆?:
∆? = ?
We can imagine that we can try to...
