Drive the expression for temperature coefficient of resistance?

To derive a value for thermal coefficient of resistance, I find the resistance R1 at one temperature T1, and the resistance R2 at temperature T2.

I can then express this coefficient as (R2 - R1) / [R1 (T2 - T1)] X 100% per degree.

Example: R1 = 50 ohms at T1 = 20 degC

R2 = 20 ohms at T2 = 500 degC

(R2 - R1) / [R1(T2 - T1)] X100% per deg = (20 - 50) / [50 (500 - 20)] X100% per deg

= - 0.125% per degC

But this assumes the change in resistance is linear. In fact, such changes often happen on a curve. To estimate the form of the curve, at least three temperature:resistance data pairs are needed.

What are the data security threats and what controls can be put in place to curb the threats?

Historically, information security solutions have focused on preventing external threats such as viruses, hackers and worms through perimeter solutions that include firewalls and antivirus software. While still aware of outside threats, companies are now coming to understand they can no longer ignore inside violations concerning data at rest. So information security and privacy is of atmost importance whether it is internal or external.

Today's employees are able to easily export sensitive files and information via email or by copying to file shares and portable media without concerning about data security and data privacy. Many companies simply do not have the resources or appropriate policies in place to identify NPI and PII and avoid inadvertent, accidental mis-steps or malicious actions from within. As companies continue to accumulate NPI and PII, they are under enormous pressure to mitigate risk and to provide data security to sensitive information before an undesirable loss occurs. Whether you call it data security, Content Loss Prevention or simply Information Security solutions & Privacy, the time has come to take steps to protect your company's data privacy.

Deployed in under 30 minutes, the Kazeon's Information Server i.e. information security solutions system discovers sensitive information contained in emails and files regardless of physical or logical location.

Can you get free PSP GO games?

To start off with, SONY is discontinuing the psp go sales to concentrate on the new ps vita. It is going to continue in North America though. The reason why it is discontinued is becuase it was a failure. Sony was offering 10 free games for the psp go in UK, while they were offering 3 free games with the psp go in USA. Recently, the PSN store was hacked, and they offered 2 free psp games. But in general, psp go games are not free. You can get free demos of games, but nothing more.

Why is there usually a plastic coating around a metal wire?

There are a number of reasons:

If the wire is electrical then it is covered in plastic as plastic provides insulation, this means that if adjoining wires come into contact the electrical current would not cause a short circuit. Normally electrical wire is cooper as it is a good conductor of electricity and does not oxidize/ rust easily.

Secondly wire hangers are covered in plastic to prevent the metal (normally mild steel) from rusting. If they were to rust, it would cause orange/ red stains on your clothes.

How does 199 buddy work?

i do not know how it works but you txt your first and last name, your suburb to 199 buddy and it sends back information on yourself. It costs $3 per msg. It isn't a sign up thing and it only charges you 1

199Buddy works outside Australia. 199Buddy operates in UK, Canada, NZ & Australia. It is a service purely for your entertainment

Edit: I actually think it's based on your text messages. When I searched for myself it came back with things I'd said in texts...but the biggest give away was "wants to get naughty with [someone], has a stunning body" which was a joke i sent to a friend where i took a photo of myself in just jeans and bra and said "let's get naughty!". This is the only way it could have picked up that i wanted to "get naughty" with my friend, or that i have a "stunning body" (i don't, lol, but thanks Buddy).

Basically. You send a text message to the Buddy service, if you are wanting to know about someone for example you would say "Who is *insert name* from *insert location*?" This is only a entertainment service, so it cannot access personal information that you would prefer to keep private at all. It is not all based on fact, it is just information picked from the internet and adapted into a funny message.

They reply within a few minutes, they are usually answers like;

"Buddy knows that *insert name here* is a blonde bombshell/stunning brunette! *Insert one of the persons internet friends names here* thinks she is beautiful, and *insert name* steals her amazing dance moves!"

OR, if you need another example;

"Buddy knows that handsome hunk *insert name here* is the most famous kid at *insert school or college here*! *Insert name here* annoys him! Checks *insert name here* out secretly! Funny!"

They would get this information just by your profile picture and your internet friends.

It is not based on text messages or anything . It is just automated replies personalised to the information they can find from the persons internet profile.

What is the speed of infared waves?

The lower frequency boundary is open to discussion; it is difficult to know where the far infrared becomes the "millimetric" microwaves. Somewhere round about 10THz (=1013Hz) The upper bound is easy - if it is just too low a frequency to see, then it is infrared. 384THz (=3.84 X 1014Hz)

Who was Hannah Arnett?

She was a great Revolutionary War girl. She basically saved the whole war. With out her we wouldn't have America. You wanna know why? This is the story:

Some important American Patriots were staying in her home. One day they were having a meeting in which Hannah wasn't invited to. She accidentally walked in and heard them talking about surrendering and going back to the British side. As soon as she heard this she called them "Cowards and Traitors." Her husband, Isaac Arnett immediately tried to dismiss her from the room but Hannah refused. she said that if he became a loyalist than she would divorce him as soon as he did. He knew she meant this. And the soldiers did too. So when they heard her threat they decided to reject Britain's offer. And that's the story of Hannah A. and the soldiers.
