| What exactly does the cold virus do to me to make me so weak? Posted: 09 Dec 2017 08:24 AM PST So, two days ago, I was a happy healthy guy who could lift 50 pound bags of cat litter, run (literally) a few blocks down to the corner store, and leap out of bed in the morning when I wake up. I now have a cold. Coughing, sneezing, phlegm, headache, etc. I am also very weak and can barely walk my body across the room. What specifically is causing this? Are all the body's resources tied up in fighting the virus or has the virus itself actually somehow made my muscles weak? In a week or so, I'll be better and back to normal, but it's weird how even though my muscles have not had time to deteriorate due to lack of use, it seems like they're only one third there.

| Is there a coating that you can put on a surface to make it easier for frost to form on the surface? Posted: 10 Dec 2017 06:51 AM PST I've seen videos of patterns painted on a sidewalk with hydrophobic paint, so that when it rains a pattern appears on the sidewalk. Could something similar be done with frost, except to attract frost rather than prevent it? Thanks. [link] [comments]  |
| Posted: 10 Dec 2017 06:49 AM PST We get rain and snow that will carry on for days at a time without let up, but hail storms only seem to last for a short period of time (at least, they do in the UK). Why is this? [link] [comments]  |
| Posted: 10 Dec 2017 04:19 AM PST Hi! Am a grade 10 student thats very confused about this. Our teacher told us its the intermolecular forces for covalent compounds that decides on wether or not the boiling point is high, but also told us that the size of the molecule did too. The books we have (and some sites on the internet) listed weight and the "space" the molecule took up as two reasons as to why the bounds became stronger, but i dont understand why its like that. Someone told me that its also because the molecules place themselves in crystal-like structures (we talked about sugar molecules). Why its like that and whats the reason that sugar places itself like crystals while for example water does. [link] [comments]  |
| Are there any predators that hunt for sport rather than for food? Posted: 10 Dec 2017 06:56 AM PST Well, my question is pretty much all there is to it. Since humans hunt for sport besides for food, so there must be some other apex predator so advanced that it doesn't need to hunt for food all the time and can actually hunt for sport.

| Where does the extra energy come from in blueshift? Posted: 09 Dec 2017 02:28 PM PST I'm currently doing A level physics where we are learning about special relativity and I was wondering, if an object is moving towards a stationary spectator at high speed (close to the speed of light) and the light from it appears to have a higher frequency (due to the Doppler effect) and higher frequency light waves have more energy, where does the extra energy come from. From the objects frame of reference, the light has less energy than it does from the frame of reference of the stationary spectator but would this not break the first law of thermodynamics?

| Why is it that magnets affected older Computer Monitors, whereas now they don't? Posted: 09 Dec 2017 12:59 PM PST When I was young my friend had a very strong magnet; when she put it in front of her monitor (those old big ones with glass screens) there were weird color distortions.

| Are there any viruses that attack other viruses? Posted: 09 Dec 2017 10:37 AM PST There are viruses that attack every kind of living cell, but do any attack other viruses? I doubt a virus cell is capible of producing other viruses within themselves, but could a virus "hijack" another virus so the victim carried the attacker's DNA as well/instead? [link] [comments]  |
| How can water evaporate before reaching its boiling point? Posted: 09 Dec 2017 11:31 AM PST You know on a hot day in the summer your driveway will be pretty hot but nowhere near 100 degrees. How is it that if you dropped a cup of water on it the water would be evaporated within a matter of minutes? [link] [comments]  |
| Why is my reflection in the mirror backwards, but not upside-down? Posted: 09 Dec 2017 09:25 AM PST I have wondered this since I was a child. I am now a full-grown middle-aged man and still don't have an answer. Please help! [link] [comments]  |
| Do aquatic animals get the "bends"? Posted: 09 Dec 2017 08:04 PM PST Why not (if they don't), and how do they deal with it (if they do)? [link] [comments]  |

| Posted: 09 Dec 2017 07:40 AM PST I tried to move my music files from my phone to PC today. The estimated time was more 40 minutes. But had I moved a single file of the same size, it wouldn't have taken more than 5 minutes. Why? [link] [comments]  |
| Is a a banana powered nuclear reactor possible? Posted: 09 Dec 2017 01:33 PM PST Since the potassium in bananas is radioactive, is it possible to have a nuclear reactor that only uses bananas as a fuel? And if you can, how many would you need to create enough power to run the average city? [link] [comments]  |
| What constitutes the choice of units in blood lab reports? Posted: 09 Dec 2017 01:38 PM PST I was looking at a lab report of a family member's, and I was especially interested in the units of the test components in her Comp. Metabolic Panel (14) test. Some of them included: Sodium; Potassium; Chloride; Carbon dioxide; Calcium. Na, K, Cl, and CO2 are measured in mmol/L, whereas Ca is measured in mg/dL. All of the tests were Serum except CO2. So what differentiates calcium from the rest? [link] [comments]  |
