| Do you weigh less at the equator because of centrifugal force? Posted: 01 Dec 2019 02:14 AM PST I am always confused be centrifugal and centripetal force. I am just going to state my thinking and help me point out the problem. At the equator your body is traveling fast in a circle and the inertia of your body makes you continue to move out-word, this is the centrifugal force. At the poles you are moving not at all or much slower in a circle so your inertia has less effect. With less out-word force the normal force, or your wieght, would have to compensate so you would weigh more. At the equator the centrifugal force lessons your weight ( not mass ) because it helps counteract gravity. [link] [comments]  |

| Do (long lasting) lava pools make any scientific sense? Or sense, for that matter? Posted: 30 Nov 2019 01:09 PM PST I have briefly recalled the game I played long ago, TES IV: Oblivion in which you get to enter demonic plains of said Oblivion. Those are always islands, surrounded by lava lakes, seas, also some smaller pools of lava on the exact islands. Lava in the game is basically water, only it is scripted to damage you and obviously has a different texture. Otherwise you are free to swim in it as long as you can regenerate your hp fast enough. There are also plenty of other games where you experience exposed, long lasting lava pools. Would that be possible on Earth? Wouldn't it just 'shell up' over time (upper layers got colder and toughen up)? [link] [comments]  |

| Can you pass/catch the flu virus to/from animals? Posted: 30 Nov 2019 09:36 AM PST Just a month or so ago, my mom and my grandma both got the flu (I'm guessing?) It may have been a severe cold but it lasted for maybe a week to a week and a half. After they get better my cat catches, what seems like, the same thing. He has snot running down his nose, he's drooling bc he can't breathe through his nose, he's lethargic, and he even had a little cough here and there. Fast-forward a few days after he's better and now I have flu like symptoms? But my symptoms have lasted almost 2 weeks now, they're better but not over. Maybe I sound dumb but I didnt think animals could catch most of human viruses? At least I've never seen it happen before. Thanks in advance for any answers anyone may have! [link] [comments]  |

| Do environmental factors change the randomness in having a male/female in sexual reproduction? Posted: 30 Nov 2019 07:41 AM PST Question may sound a bit convoluted. i learned that the chances of giving birth to a male or female in sexual reproduction is always exactly 50/50. there is absolutely no way to control those chances in nature. that sounds hard to believe that something so important in nature is so random... say you have a population of an animal. there are very few females, so reproduction rates are low, and competition among the many more males is extremely fierce and high. maybe this goes on for generations, could anything happen to the chances of having a male/female? maybe somehow, the chances of having a female increase so the population can grow in numbers faster and to alleviate competition. so maybe now the chances of males to females is a 35/65% chance... CAN this happen, DOES it happen? if so, how? [link] [comments]  |
| What is the flux gathering factor? Posted: 30 Nov 2019 09:05 AM PST Not sure if this is the right place to post this, but what is the flux gathering factor of a material or in a medium? A google search only shows magnetic flux linkage - is that the same thing? How would you calculate it in a medium subject to a uniform field? Any help is appreciated. [link] [comments]  |

| How would a graviton enact an interaction with a photon near a black hole? Posted: 30 Nov 2019 02:43 AM PST So I was in class a couple of days ago and learned how the speed of information and causality is at c, (~300,000,000m/s). But I had a question regarding how photons would be pulled into a black holes event horizon if the speculated gravitons max speed is c. Say we have a relatively small black hole, and a photon is travelling near it, surely a graviton to enact an interaction between the photon and "attract" it to the black hole would have to catch up to the photon which would mean it travelling faster than c. And also, the information that there is a photon near the black hole would require time to be "processed", in which time surely the photon would already be outside of the black holes gravitational field, far before a graviton can be made aware of the photon to enact an interaction? Thanks for responses in advance! [link] [comments]  |
| How do intestinal microflora adapt to dietary changes? Posted: 29 Nov 2019 11:48 AM PST When a person changes their diet, like when trying to lose weight by shifting away from processed foods to more whole foods, how does that affect the populations of different bacteria in their digestive tract? How long does it take for the populations to adapt? [link] [comments]  |
