Compute the uncertainty in the linearised y values using the symbolic manipulation we have developed in the activity and using the strings "M1", "M2", "R", "uM1", "uM2", and "uR" in your sympi Symbols. 

Print the resulting symbolic expression for the uncertainty in the linearised values and copy and paste (directly and without any editing) that into the text cell below.(E.g. if your expression for the uncertainty is u_expr_y, then add the statement "print(u_expr_y)" 

You also determine an array of the numerical values of all your y data points for the linearisation. Use print with this array to print this array of values in Python and copy and paste (directly and without any editing) here. (E.g. copy paste the output of print(Y) if Y is the result of calling the function returned by lambdify applied to your expr_y). 

Define expr_y to be a correct symbolic representation of the prescribed linearisation given in the practice tasks (). Use the strings "M1","M2",and "R" for your symbols (e.g. SM1=sp.Symbol("M1"), etc. and expr_y=some mix of symbols )

After doing, so print expy_y by using (exactly) the line "print(expr_y)."

Lastly, copy and paste your output (directly and without any editing) into the text box below. NOTE: Only copy the output of the print statement, ignore any other output your code might produce.

In exercise 2 you used force measurements at various separations, which lines of code correctly setup symbolic expressions for our desired  x and y in the variables expr_x and expr_y given

SM1=sp.Symbol('M1'
)
SM2=sp.Symbol('M2'
)
SR=sp.Symbol('R'
)
SF=sp.Symbol('F'
)
SUM1=sp.Symbol('uM1'
)
SUM2=sp.Symbol('uM2'
)
SUR=sp.Symbol('uR'
)
SUF=sp.Symbol('uF'
)

Which of the following is a correct python plot for the data set in Exercise 2?

In exercise 2, the first task you have is entering the data in SI units. To handle the masses is pretty easily achieved via something like 

m1=100
m2=1000
um1=1
um2=10

but entering the data in SI involves a bit more effort. Which of the following could be used to achieve this?

In the practice exercises, you computed the uncertainty in Pressure computed from 

with:

.

What was the result you obtained?

Rubidium (Rb) is an element with 37 protons.  Which of the following number of electrons describes a positive ion of Rubidium?

An object always has an integer multiple of e, the fundamental unit of charge.  This is called:

The gravitational field is a:
