Can sound waves travel through objects?
May 27, 2015
Can sound waves travel through objects
lilly - USA (26032)
Yes, besides traveling through air, sound travels through materials and objects. For example, you can hear sound from another room as it passes through the wall. Also, you can hear sound underwater.
Fields of study for elecrto-optical engineering
May 26, 2015
Hey sirs, madams good day to you.
I wana to know more of about what specific fields of study are there under elector-optical engineering
and pleas give me explanations about each sub-fields.
Assamen - Ethiopia (26031)
Electro-optical engineering requires knowledge of General Physics, Optics, Mathematics, and various Engineering topics.
In Electro-optical engineering, you may work with optical devices, electrical sources of various types of radiation, and detectors of that radiation. For example, you may need to create infrared radiation and have IR lenses to focus the light, and then be able to detect it.
Where is Alfred Deakin High School?
May 25, 2015
Where is Alfred Deakin High School on the high school list
jay - Canada (26030)
I added your school to the List of Champion High Schools.
Any barriers for becoming a technical writer?
May 24, 2015
I have no engineering degree but have been a maintenance professional, a machinist and designed and built many special purpose machines large and small over a 35 year career. Are there any barriers to me becoming a technical writer? Any certification requirements? Is it possible to do this free lance?
Thanks in advance for any advice!
Larry - USA (26028)
Consider the companies you've for in the past. Did they have documentation for the various devices or machines, such as repair manuals, user manuals, etc?
If not, perhaps they could use such documentation or someone knowledgeable to work on their documentation. This is a good area for freelance or contract work.
A few large companies may require certification or a degree in writing, but it usually is not a roadblock.
A good place to start and to get information about the business is through the Society for Technical Communication. Find a chapter in your location and check out a meeting. You can also find out about jobs in your area.
Best wishes for success in your new career.
Send me notes and questions
May 23, 2015
i want u guyz to send me note and questions so that i can answer them all
Alfred - Malawi (26024)
The best thing to do is to go through the Chemistry lessons and try to answer the Mini-Quiz questions.
Force of the earth on a girl
May 23, 2015
The force of the earth on the girl is mg = 9.8 x 50 = 490N
David - Australia (26026)
Although you can calculate the gravitational force between a person and the Earth, it is easier to use the equation F = mg, which actually gives the weight of the person on Earth.
See: Mass, Weight and Gravity for more information.
Types of electromagnetics
May 22, 2015
how many types of electromagnet are?
Can we divide electromagnetism/electromagnet/electromagnetics?
Please send the answer..
Ibrahim - India (26020)
An electromagnet is a device that creates a magnetic field (or electromagnetic field) from current passing through a wire coil wrapped around an iron core. There are many possible shapes and configurations of electromagnets.
Electromagnetism is the study of the electromagnetic force. Electromagnetics is usually the study of electromagnetic equations.
Generating electricity with magnets
May 22, 2015
On what principle does passing a wire through magnetic field works
Sir I am in class 9th and got an assignment to make a project on "Generating electricity with magnets"
Under the following headings
Sir can you please help me out.
taha - India (26021)
The Lorentz Force on an electric charge occurs when the charge moves through a magnetic field.
See Magnetism and the Lorentz Force and Moving Electrical Charges Create Magnetic Field to help answer your questions.
Wants good grades like twin sister
May 21, 2015
Hi!I recently I got an E in physics, biology and chemistry and I do many past papers. I have a twin and she gets A's and B's in her tests and she hardly revises. Every time I cry my self to sleep as my parents are always nagging me into trying harder as my sister is doing well in school. I really need some advise to how I could ppssibly get good grades. I am starting to give up on life and school and I am starting to stop revising altogether. I just need ur help as I want to become a vet and in order to do thia I need A's in science and I am getting E's. I am in year 9 and we start our GCSE's in year 9
Nihal - UK (26017)
Sometimes twins have different capabilities and talents. The worst thing to do is to try to compete with your twin. Instead, seek to do the best you can do.
Also, consider what areas in school where you really excel. Your talents may be in other areas than your twin's talents.
Consider the reasons you do not do well in the science classes. Do you understand the material? Do you have trouble with tests? Do you have good study habits? These may be areas in which you can improve.
The fact that you have to study harder than your sister can make you stronger in the long run, especially if you don't give up.
Tell your teachers you would like better grades, and ask them for pointers on how you can improve. In fact, you might even ask your sister if she can give suggestions on how you can get better grades. Any type of advice can only help you.
Don't get discouraged. Even Einstein didn't do well in school. Also, make sure you are aiming in areas where you have the most talent.
I am sure you will be able to excel and reach your dreams as a champion.
I hope these ideas help.
Need to understand Physical Science
May 21, 2015
would like to understand physicl science from basics
samuel - Kenya (26018)
Physical Science consists of the studies of Astronomy, Chemistry, Physics and Earth Science.
See our lessons on Succeed in Understanding Physical Science. They will give the basics in the various science areas.
Validating the acceleration due to gravity
May 21, 2015
I am still struggling with gravity.
Has the 9.8 m/s ever been validated with real data?
When you leap out of an aircraft you go from nothing to something as Newton observed with the apple.
But after a very brief period of acceleration you slow the rate of acceleration as you get closer to the Earth.
Drag is real. How did scientists ever validate the 9.8 meter thing?
Bear with me. My last physics class was in 1959 and I only got a C.
Allen - USA (26019)
The acceleration due to gravity on the Earth is set at about 9.8 m/s^2. This number is an average value, since the force varies in different locations. It has been measured by numerous experiments and compared with the theoretical value.
When an object is dropped, starting at zero velocity, it increases its speed at the rate of 9.8 m/s^2. However, air resistance can slow down the object as it falls. The resistance is a function of the speed of the object.
See Work Done by Gravity Against Inertia and Air Resistance for more information.
Need basic Physics help

Temperature and organic molecules
May 20, 2015
What is the relationship between temperature and the properties of organic molecules?
Banele - South Africa (26016)
Temperature can determine whether organic molecules are as a gas, liquid, or solid. Also, at certain temperatures, the chemical reactions may occur with other materials. For example, wood will burn or oxidize when the temperature is high enough.
What if I shoot an attacker?
May 19, 2015
what if i shoot an attacker and dies on spot,what action should i take immediately?
mandela - Kenya (26009)
If your life was being threatened--or that of your loved ones--it may be necessary to shoot the attacker. If it is simply a case of someone breaking into your house to steal and there is no real threat, it is better to show your weapon and try hold him until the police arrive.
If you kill an attacker, should call the authorities. However, sometimes you would have to prove you were being attacked.
It would be a good idea to check with your police or authorities to find out the proper procedures.
Best wishes. I hope you never get into this situation.
