Table of contents
Preface
General
This module is part of a
book
(or collection) designed to make physics concepts accessible to blind
students. The collection is intended to supplement but not to replace thetextbook in an introductory course in high school or college physics.
This module explains various units of force in a format that is accessible to blind students.
Prerequisites
In addition to an Internet connection and a browser, you will need the
following tools (as a minimum) to work through the exercises in these modules:
 A graph board for plotting graphs and vector diagrams (
(External Link) ).
 A protractor for measuring angles (
(External Link) ).
 An audio screen reader that is compatible with your operating system,
such as the NonVisual Desktop Access program (NVDA), which is freelyavailable at
(External Link) .
 A refreshable Braille display capable of providing a line by line tactile output of information displayed on the computer monitor
(
(External Link) ).
 A device to create Braille labels. Will be used to label graphs
constructed on the graph board.
 The ability to create tactile graphics as described
here .
The minimum prerequisites for understanding the material in these modules
include:
 A good understanding of algebra.
 An understanding of the use of a graph board for plotting graphs and
vector diagrams (
(External Link) ).
 An understanding of the use of a protractor for measuring angles (
(External Link) ).
 A basic understanding of the use of sine, cosine, and tangent from
trigonometry (
(External Link) ).
 An introductory understanding of JavaScript programming (
(External Link) and
(External Link) ).
 An understanding of all of the material covered in the earlier modules
in this collection.
 An understanding of the creation and use of tactile graphics as
described
here .
Viewing tip
I recommend that you open another copy of this document in a separate browser
window and use the following links to easily find and view the figures while you are reading about them.

Figure 1 . SI base units.

Figure 2 . Examples of SI derived units.

Figure 3 . Mirror image of the image from the file named Phy1150a1.svg.

Figure 4 . Nonmirror image of the image from the file named Phy1150a1.svg.

Figure 5 . Keyvalue pairs for the image in the file named Phy1150a1.svg.
Supplemental material
I recommend that you also study the other lessons in my extensive collection
of online programming tutorials. You will find a consolidated index at
www.DickBaldwin.com .
Creation of tactile graphics
The module titled
Manual Creation of Tactile Graphics explains how to create tactile graphics
from svg files that I will provide.
Questions & Answers
find the 15th term of the geometric sequince whose first is 18 and last term of 387
The given of f(x=x2. then what is the value of this f(3) 5f(x+1)
hmm well what is the answer
Abhi
how do they get the third part x = (32)5/4
can someone help me with some logarithmic and exponential equations.
sure. what is your question?
ninjadapaul
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X6)^2
so it's 20 divided by X6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
is it a question of log
Abhi
I rally confuse this number And equations too I need exactly help
salma
But this is not salma it's Faiza live in lousvile Ky I garbage this so I am going collage with JCTC that the of the collage thank you my friends
salma
im all ears I need to learn
Sherica
right! what he said ⤴⤴⤴
Tamia
what is a good calculator for all algebra; would a Casio fx 260 work with all algebra equations? please name the cheapest, thanks.
algebra 2 Inequalities:If equation 2 = 0 it is an open set?
or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.
Al
if A not equal to 0 and order of A is n prove that adj (adj A = A
rolling four fair dice and getting an even number an all four dice
Differences Between Laspeyres and Paasche Indices
No. 7x 4y is simplified from 4x + (3y + 3x) 7y
how do you translate this in Algebraic Expressions
Need to simplify the expresin. 3/7 (x+y)1/7 (x1)=
. After 3 months on a diet, Lisa had lost 12% of her original weight. She lost 21 pounds. What was Lisa's original weight?
what's the easiest and fastest way to the synthesize AgNP?
I start with an easy one. carbon nanotubes woven into a long filament like a string
Porter
many many of nanotubes
Porter
what is the k.e before it land
Yasmin
what is the function of carbon nanotubes?
Cesar
I'm interested in nanotube
Uday
what is nanomaterials and their applications of sensors.
what is system testing?
AMJAD
preparation of nanomaterial
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
good afternoon madam
AMJAD
what is system testing
AMJAD
what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field .
1Electronicsmanufacturad IC ,RAM,MRAM,solar panel etc
2Helth and MedicalNanomedicine,Drug Dilivery for cancer treatment etc
3 Atomobile MEMS, Coating on car etc.
and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change .
maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^15
Prasenjit
can nanotechnology change the direction of the face of the world
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
how did you get the value of 2000N.What calculations are needed to arrive at it
