## How to Submit Online Homework: CAPA
Instructions

The numbers used in the CAPA
problems may be different than what were given in the book.
You may repeat
the problems you missed, usually up to four times.
Entering the
wrong units and the wrong number of significant figures don't
count against your four attempts but you have to get them right
to get the problem right.
Do not open
multiple sessions or browsers. Be sure to exit properly each
time to terminate a session.
You may log on
as many times as it takes to get the set done.
Avoid using your
browser's **Reload** button as it may re-submit an incorrect
answer and use up one of your tries. Use the **Reload**
button at the top the assignment.
Always use basic
SI units unless otherwise specified. Units such as
"micro-Coulombs" are entered as "uC", "kilograms" are entered as
"kg", "Newtons/Coulomb" are entered as "N/C", and "meters per
second squared" are entered as "m/s^2".
Answers
requiring scientific notation such as 3.0× 10^{-8} can
be entered as "3.0E-8".
Hints will may
come up for some problems if you submit an incorrect answer.

Spring, 2014

- All assignments and dates are subject to change. You may need to hint your browser's "reload" button to get the most recent update.

- Reading should be done
*before*the topic is covered in class. Not all reading and homework material will be directly covered by the lecture. - Homework is due at the start of class on the due date. Everything else is considered late.

The homework problems listed in red in the table is to
be done on the web using a **C**omputer-**A**ssisted **P**ersonalized
**A**pproach, or **CAPA**. You have been assigned CAPA ID numbers which you must
use, in addition to your student ID number, to log onto the
system. The homework assignments are simply textbook problems
with the * different * values for the variables randomly
chosen for each student. You can work the problems out using the
book values before logging in or you can log on and print out
your personalized assignment before submitting answers via the
web. Solutions to the book version of the problems will be
accessible through the links below once the due date has passed.

**Access via web**

1. Point your browser to http://capa.fiu.edu

2. Choose**phy3107** from the pop-up menu.

3. Enter your Student Number followed by 00 (the system requires a 9 digit student number) and your CAPA ID. To get your CAPA ID number click here. Find your name and use the corresponding CAPA ID number for the homework set you are doing.

4. Click on the appropriate button to try your set.

5. You may look back at old sets at any time to see the correct answers by using the "View previous set" botton and entering the set number.
