For some reason, whenever I exhale through my nose I start to feel a bit of pressure on the back of my head. I also feel a burning/tingling sensation on the outside bottom area of my mouth, as well as a bit of numbness in my left jaw area. i can feel each of these symptoms every time i exhale, but somehow these symptoms stop when i exhale through my mouth. And it gets weirder: I get all of these symptoms when i look at a computer screen or phone. My guess is that I am having a migraine headache and somehow exhaling through my nose is triggering the migraine (numbness/tingling are symptoms of migraine)? or could it be that there is a problem with my breathing? I am really confused and it's really hard to even do my school work online. I must solve this as soon as possible. Any help or ideas of what is going on is greatly appreciated. thankyou. 

I am extremely sensitive to electronics because the artificial lights will trigger a migraine. As a result, I cannot use a computer or a phone without having an anxiety attack and extreme face inflammation and, of course, a mild headache (all of which are entirely due to the migraine). Someone please help me.

Hello,

I have a really severe case of migraine, in which they are triggered almost instantly when I use my computer or iPhone, for example. As soon as I go on my phone, I start to get a host of symptoms:

•I begin to feel a tingling/irritating sensation in my mouth area

* My left jaw area begins to jerk and feels numb

• my eyes become extremely fatigued and red (I'm pretty sure my eye bags are also caused by migraines since I get at least 8 hours of sleep every day).

• Then I will get a runny nose and a nasal congestion.

•Mild headaches

•brain fog

•difficulty speaking

•difficulty thinking/slower thinking (temporarily)

• anxiety

• depression

•massive face inflammation (which I recently discovered is why i have acne, especially around my mouth)

•nasua

And the list goes on... Does anyone have an idea of how I can prevent migraines while I use electronics? I bought there specs glasses, but they are not really helping. The allay lamp did help a bit, and Excedrin significantly decreased the symptoms, but I want to completely prevent all of the symptoms—without having to avoid electronics because that is just not possible in the 21st century. I have not tried any other medications, but I have an appointment with my physician soon. In the meantime, I would greatly appreciate any helpful answers or ideas that could help. Thank you. 

I am doing an experiment that requires a material that completely blocks/reflects a computer screen. Initially, I believed aluminum foil would do the trick, but the light still penetrates through several layers of it. The best thing I found so far is a 300-page book, and I would like to find something a bit slimmer. I will be extremely grateful if somebody solves this for me because I have been unsuccessful thus far. Thank you. 

I am extremely sensitive to artificial lights (e.g., LED and fluorescent lights), and I cannot use electronics without my face becoming extremely irritated. Sunscreen helps quite a bit, as well as blocking my face with a UV-blocking cloth. However, this does not completely eliminate the irritation, and I was wondering what can I use to completely shield my face from the LED light on my MacBook?

As a 20-year-old male, I have quite a bit of acne (mainly on the area around my mouth), but my situation is much more complicated than a typical acne problem. The source of my acne seems to be using electronic devices (e.g., phone, laptop, monitor). I know it sounds ludicrous—but I have noticed it for a few years, and I am absolutely sure of it. I know this because I have tried everything. And the only thing that works for me is being away from electronic devices; what works best is being outdoors, night or day. Every day, after I wake up or shower, my face feels optimal. If I go on my phone even for 20—30 minutes after I wake up or shower, the area around my mouth will become extremely red and inflamed, causing an unbearable burning sensation. If I do not go on my phone after I wake up or shower, my face will continue to feel optimal. 

However, I must mention that the acne and burning sensation around my mouth are not the only symptoms. Here's a list of a few more symptoms that I experience when I am on my phone or laptop (the longer I am on these devices, the more severe they become): 

• brain fog

• numbness/puffiness in my left jawline area

• eye fatigue 

• face feels hot

• itchy throat 

• watery eyes

These symptoms are from personal, everyday experience, and they all go away or begin to go away when I go outside, for example. If anyone has an idea of what's going on, I will love to hear it. Thanks to anyone reading this. 

For example, if I am converting CAD/USD (Canadian dollars to U.S dollars) and the exchange rates is 1.2, does that mean 1.2 CAD equals 1 USD or 1 CAD equals 1.2 1.2 USD?

I would solve this question by first converting the 200 g copper to 0.2 kg. Then solving with C = q/mt and I get 390 J/(kg•K). I know that if you solve it without converting g to kg you still get the right answer

(0.39 J/(g•°C), but how if you are using the wrong units (g•K)?

Assume there's no friction

These are two problem examples:

A sailor pulls a boat full of cargo using a rope angled at 60.0°. The sailor applies 1x10^3 of force and pulls the boat for 30.0 m to the end of the dock. How much work does the sailor do?

A sailor pushes a 50.0 kg barrel along a dock. He then pushes it up a 10.0 m gangplank to the deck of a ship. The sailor applies his force parallel to the dock. The gangplank makes an angle of 30.0° with the dock. Assume that the gangplank is frictionless. How much work does the sailor do?

This was a question on a test that I got wrong. My answer was "It increases her angular momentum." The other answers were A) It makes her fall more slowly B) It decreases her moment of inertia. and c) It decreases her angular velocity. I thought bringing in your arms and knees makes the rotation faster, which also makes the Angular momentum larger. Can someone please explain this problem to me.

3x-9/x-3= -3x/2 I got x= -2 or x= 3 am I right or wrong?

Every time I try to fill the object with color only the stroke is changed and not the fill, does anyone know how to fix this?

Find (3f+g) (-4) using method 1: First combine the functions. Then you can plug the given value into the simplified function.

f(x) = x+1; g(x) = (x+3)²

This is the first step: 3(x+1) + (x+3)²

3x+3 + (x+3)²

3x+3 + x² + 6x +9

I don't know where the 6x came from can someone please explain this to me.

What is the value of the following expression 4x - y² when x = -3 and y = -2

I set the problem up like this (4 • -3) - (-2²) and got - 8 but I got it wrong does anyone know where I made a mistake?
