Question
1) A standard deviation of your measurements on some distance (i)____ and the standard deviation multiplied by confidence coefficient (ii)___.
(i) does not have units (ii) has units of distance
(i) does not have units (ii) also does not have units
(i) has the units of distance (ii) does not have units
(i) has the units of distance (ii) also has the units of distance
2) At which point in the uncertainty calculations should you round up numbers? F is a function of X and Y.
For each of X, Y, F/X, F/Y, and F
For each of F/X, F/Y, and F
For each of X, Y, and F
For (F/X) * X, (F/Y) * Y and F
At the very end when you actually determine F
None of the above
3) Given
obtain the expression for 2.
None of the above
4) Given
the slope of the plot of ln(/V) versus t is
RC
1/RC
V / RC
/ VRC
None of the above
5) For which of the following cases do you use the total differential/difference formula to determine the uncertainty of F?
F is independent of X and Y and F can be directly meausred
F is independent of X and Y and F cannot be directly meausred
F depends on X and Y and both X and Y can be directly measured
F depends on X and Y but both X and Y are not directly measurable
C and D, but not A and B
None of the above
A.(i) does not have units (ii) has units of distance
B.(i) does not have units (ii) also does not have units
C.(i) has the units of distance (ii) does not have units
D.(i) has the units of distance (ii) also has the units of distance
Explanation / Answer
(1) standard deviation takes the unit it measures
confident coefficient is dimensionless if it is multipled by distance it will also have the units of distance
Option-D
(2) Option - E at the very end
(3) Option - A (not sure) it could have been helpful if a math expression is given instead
(4) Option - B
