Step 1
The Millikan experiment consisted of finding the minimum possible charge by obtaining the smallest drop possible. He then inferred that the charge of the electron was due to the fact that it was not possible to find a lower charge.
Drop #ChargeA 6.9×1019CB 9.2×1019CC 11.5×1019CD 4.6×1019C
Step 2
We must find a number that when we divide in the four drop # it would give us a quotient that is a whole number. We can do this by doing trial and error.
By trial and error, we found out that the number is 2.3×1019C
DROP A: 6.9×1019C2.3×1019C=3
DROP B: 9.2×1019C2.3×1019C=4
DROP C: 11.5×1019C2.3×1019C=5
DROP D: 4.6×1019C2.3×1019C=2
Answer: 2.3×1019C

Millikan experiment consisted in finding the minimum possible charge by obtaining the tiniest drop possible.
Then, he inferred that was the charge of the electron, given that it was not possible to find a lower charge.
Given these recorded data:
6.91019
9.21019
11.51019
4.61019
You must find a number that divide the four data and yields a whole number.
This number is 2.31019.
In that way you find:
6.910192.31019=33 electrons
9.210192.31019=44 electrons
11.510192.31019=55 electrons
4.610192.31019=22 electrons
And you can conclude that the charge of the electron is 2.31019
Answer: 2.31019

Step 1
The idea is the number of electrons is a whole number. So to find a charge that a “whole multiple” will satisfy all the charges on the drops.
Step 2
Let X = the charge….A, B, C and D are whole.
AX=-5.7×10-19C.
BX=-7.6×10-19C.
CX=-9.5×10-19C.
DX=-3.8×10-19C.
Difference between BX and CX is 1.910-19.  That’s the smallest difference.
Step 3
Therefore,
3×(-1.910-19)=-5.7×10-19C
4×(-1.910-19)=-7.6×10-19C
5×(-1.910-19)=-9.5×10-19C
2×(-1.910-19)=-3.8×10-19C.
So the charge of imaginary electron is -1.910-19C

As part of your work out, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when u push the platform, you compress the springs. You do 80.0G of work when u compress the springs 0.200m from their uncompressed length.
a) What magnitude of force must u apply to hold the platform in this position?
b) How much additional work must you do to move the platform 0.200m farther, and what maximum force must you apply?

Can trigonometric substitution be used to solve this integral?
The integral in question is
x+19x2+6x+5dx
I first completed the square in the denominator giving (3x+1)2+4 and proceeded to perform a u-substitution with u=3x+1, du=3 dx, and x=u13. After simplifying, I was left with
19u+2u2+4du
It is at this point I used trigonometric substitution with u=2tanθ and du=2sec2θdθ (I'm aware the integral can be written as 19uu2+4du+192u2+4du and solved this way). After performing the trig substitution, I was left with
19(tanθ+1)dθ=19ln|secθ|+19θ+C
19ln((3x+1)2+42)+19tan1(123x+1)+C
which is incorrect. The correct answer is
118ln(9x2+6x+5)+19tan1(123x+1)+C
What went wrong with my trig substitution?
