(when conserved):
A characteristic
(combination of measurements)
that holds constant
from PLACE to PLACE
while a system
continues to
exhibit signficant,
yet
symmetric,
changes over time.


No HW due first class.

Making sure of the mathematics:
(1) we'll stretch
our legs
and put the
Dif. Eq. for SHO through its paces;
(2) then we'll
shake some hands
and be pleased to meet a new vector technique:
(the unit vector notation for vector
multiplication)

Below,
a bit of
required reading.
Please note.
The reading is not necessarily easy
nor fun,
but it has
actually been reported,
by some students,
to be somewhat helpful
and clarifying:

Two ways to Multiply Vectors
The e, the eCharge, &
the eForce

READ in HRW: Chapter 21 (Coulomb's Law)
(Don't stress about section 223; all you really need to know is the title: charge is conserved.)
Chapter 22 (Electric Fields)
You do NOT need to read these 2 sections: 225 (E. Field Due to Charged Disk), 227 (Dipole in EField)
In 226, the improtant part is the opening two paragaphs. All that stuff about "Measuring the Elementary Charge"
and "Inkjet Printing" is cool, but not required reading
That's a bunch of reading. Leave time for it.

HW 13:
Interference & Power
This is an expansion and elaboration of the questions we skipped from HW 10.

Midterm Prep

READ HRW: Chapter 3, section 3 (Multiplying Vectors)
MIDTERM TOPICS:
 Doppler (practice all four cases)
 1D wave interference & harmonics
 Acoustic* intensity, power, & energy
 Electrostatic Force on pointcharges
 Dot products & cross products
(NOTE: "acoustic" means "sound" as an adjective.)

HW 12:
Mathematical Mthods II: Vector Multiplication
HW 13 (optional):
Coulomb's Law: HRW Chapter 21:
QUESTIONS #9 & #10; & PROBLEMS #3 & #13
Problem 13 is a CHALLENGE PRBOLEM.
Here's a HINT: the y coordinate will have to be zero.
The reason is that, if the two forces cancel, they must be exactly opposite, i.e. colinear.
This is only possible if the three pointcharges are all in a row.
(HW 13 was posted late, so it's optional, but it will be useful for exam prep & you can get points
for it if you hand it in.)
