| Does physical size have any effect on resistance to illness? Posted: 10 Sep 2018 07:22 AM PDT Actually a Parks and Rec episode got me thinking. The super fit character Chris catches the flu, and claims that due to his low body fat and lean muscle his symptoms are worse than they might be in an average person. So would physical size have any effect on the likelihood of catching something like the flu or a cold, and have any bearing on either duration or severity? And would there be a difference if the person were obese and sedentary or muscular and fit? [link] [comments]  |

| Will a combustion engine running "lean" tend to overheat? Posted: 10 Sep 2018 10:30 PM PDT A pilot once told me that internal combustion engines with too low fuel:air ratio will often run hotter than usual. Apparently this is a problem for small aircraft changing altitude quickly. Can anyone confirm or deny this phenomenon, and offer an explanation? [link] [comments]  |

| Posted: 11 Sep 2018 07:45 AM PDT Basically, is an oxygen atom in the atmosphere more likely to bond to Cl- than to O2 or is the rate of bonding between both essentially the same? [link] [comments]  |

| How is louder sound different from soft sound? Posted: 11 Sep 2018 02:59 AM PDT Generally we say sound travels at the same speed in the air, regardless of amplitude. But in order for us to hear loud sounds, our eardrums must be pushed stronger. This, I suspect, is achieved by air molecules hitting the eardrums harder, which itself is achieved by having the air molecules move faster prior to collision. Does this increase in volume not affect the speed of sound? [link] [comments]  |
| Why don't ants die away from inbreeding? Posted: 10 Sep 2018 09:30 PM PDT Incest increases the chances of genetic disorders drastically, so why can ants have one mother for generations? [link] [comments]  |

| Posted: 10 Sep 2018 05:54 PM PDT The coil is wired in series between Vcc and the collector of an NPN BJT. The base of the BJT is fed a sine wave (CW). See figure here: http://spaz.org/~magi/elec/class-a-amp.png Does the magnetic field around the coil reverse direction every half-cycle? Or does it simply vary in magnitude? I have asked two physics professors this question and gotten different answers. Thank you! [link] [comments]  |

| In what ways will a delay of a space launch increase the total cost of a launch? Posted: 10 Sep 2018 04:06 PM PDT Re: NASA's InSight Mars lander. In 2016 NASA decided to spend $150 million dollars to delay the launch of InSight until May 2018. The lander was in storage until the next launch window, but why would the total cost of the launch balloon by that much in the interim? [link] [comments]  |
| Does a high metabolism increase risk of cancer? Posted: 10 Sep 2018 08:16 AM PDT Since a high metabolism gives you higher cell division and cancer happens when cell division has a mistake, logically higher division gives more cell divisions to go wrong? [link] [comments]  |
| How do scientists know how far away outer-space radio waves are from? Posted: 10 Sep 2018 07:42 PM PDT In this article, it states that the radio waves are from billions of light years away. How do scientists determine this? [link] [comments]  |
| What form of energy production produces zero greenhouse gases? Posted: 10 Sep 2018 08:34 PM PDT I know the obvious answers is solar and wind, but if you take in account production (especially photovoltaic cells) it takes quite some time for these form of energy production to be greenhouse gas neutral.I know nuclear power is carbon neutral, but considering how it admits water vapor it doesn't seem to be greenhouse gas neutral. From reading NOAA.gov and Wikipedia it seems that only oxygen and Nitrogen are considered to be non-greenhouse gasses.So what is a form of energy production that produces zero greenhouses gasses? From reading NOAA it seems that water vapor may be negligible. [link] [comments]  |
