- The average temperature outside airplanes at 30,000ft is -40° F to -70° F (-40° C to -57° C). The average causing speed is 575mph. If speed=energy and energy equals=heat, is the skin of the airplane hot because of the speed or cold because of the temperature around?

| Why do capacitors in series not just act as one capacitor with the center plates being null? Posted: 07 Apr 2021 07:40 PM PDT If my understanding is correct at its most basic definition a capacitor is made of two metal sheets not in contact with each other with an imbalance of charges. If two capacitors are in series wouldn't the plates closest to the battery on each capacitor just form a capacitor with the middle plates being ineffective since there is no actual contact with the circuit?

| Posted: 07 Apr 2021 10:10 AM PDT Recent studies have indicated that the AstraZeneca COVID-19 may be associated with an increased risk for a specific type (CVST) of blood clots. The risk seems to have a higher correlation for individuals that have low platelet counts. Given that blood platelets are the mechanism for blood to clot, why would lower levels lead to a higher risk for these CVST clots? [link] [comments]  |
| Are Type Ia Supernova explosions of non-binary and not accreting White Dwarfs possible? Posted: 07 Apr 2021 06:58 AM PDT I've watched a lecture by an astrophysicist about compact objects, where he said that there is a hypothesis that some very massive fast-rotating neutron stars can collapse into BH because of loss of their angular momentum and hence increasing density. Is there a theory where a fast-rotating near-Chandrasekhar mass White Dwarf can go Supernova because of loss of its angular momentum instead of accreting the required mass? [link] [comments]  |

| What countries are testing wild mice for COVID-19? Posted: 07 Apr 2021 12:45 PM PDT And does anyone have links to those results? Considering wild mink in utah were verified to have it (https://promedmail.org/promed-post/) and mice are minks favorite prey, what are the chances that wild mice already have it, and maybe have this variant: https://www.biorxiv.org/content/10.1101/2021.03.18.436013v1 [link] [comments]  |
| Does antigenic shift (viruses combining/interacting) ever result in non-viable offspring? Posted: 07 Apr 2021 02:59 PM PDT If a horse and donkey mate they can produce offspring but that offspring can't breed. Is there anything like this with viruses? Mixing analogies a bit here... If someone is infected with virus A ("horse") could you theoretical infect them with virus B ("donkey") to interfere with the infection and make an virus C ("mule")? [link] [comments]  |
| Do tendons become stronger with exercise? Posted: 06 Apr 2021 06:46 PM PDT Much like how muscles become stronger through training. Do the tendons become stronger through exercise and conditioning? [link] [comments]  |
