Are addictions hereditary? Am I more susceptible to certain addictions based off of whether or not my parents were addicted to a certain thing?

Posted: 17 Feb 2020 06:22 PM PST

For example, if my parents were alcoholics would I be more susceptible to becoming one myself compared to someone else who's parents weren't alcoholics?

Does pressing a modern car's gas pedal increase the amount of fuel entering the engine over a flat period of time, or does it increase it by a set amount for each pulse of fuel injection?

Posted: 17 Feb 2020 06:50 PM PST

It is my understanding that opening a traditional throttle lessens a physical restriction of fuel-flow (gasoline) or air-flow (diesel) to the engine, but with modern fuel injection controlled by computer I'm curious whether it's metered by volume/time or volume/intake cycle.

It seems to me that if it is the former, the engine might eventually stall with not enough fuel per ignition to sustain engine RPMs. However, if it is the latter, acceleration might get out of control in a feedback loop.

There are 50-1000 galaxies in a cluster; how many galaxy clusters are there in the universe?

Stupid question, I know, but Google isn't telling me the answer. Thanks!

On average, what percentage of their contribution to GDP are workers paid in the United States?

Posted: 17 Feb 2020 02:15 PM PST

I'm going to try and describe my question/thought process in terms of things I know, so forgive me if a lot of what I say is obvious to anyone who's studied economics.

I took a business economics class last semester where we learned about mutually exclusive alternatives (MEAs). I've been thinking a lot about workers wages in terms of MEAs. When deciding where to invest money, a company establishes what's called a 'Minimum Acceptable Rate of Return'. I don't know how that's determined, but generally speaking an individual or entity can invest in mutual funds and make about a 7% ROI in the long term. I know that probabilistic risk plays a huge part in decision making, but let's just keep it simple.

This means that any investment that doesn't make a 7% ROI is a waste of money and that includes workers wages. I would think then, that most workers are paid about 90% of their contributions to GDP...or company revenue...or something. I'm a capitalist to the bone, but if we stray much farther from that I would say that the average worker is definitely being taken advantage of.

Maybe contribution to GDP isn't the thing to measure against, but is my thought processes generally correct? And do we know what percentage GDP (or whatever the appropriate metric is) workers are paid on average? Thanks.

How is data sent through frequencies?

Posted: 17 Feb 2020 03:42 PM PST

I know that a carrier frequency is what a receiver and transmitter use to communicate but how is a 1 or 0 seen in that frequency? i.e. if a carrier frequency is a wire what produces the high or low?

Why must you deflect your rudder to maintain course on a Great Circle?

Posted: 17 Feb 2020 02:57 PM PST

I understand that a Great Circle represents the shortest distance between two points on the surface of a sphere, and that if represented on a 2D map, it looks curved.

I also understand that if you were to sail/fly straight on a course other than a cardinal direction, your heading would gradually change.

Why do you have to actually change your ground track (as in curve your course--not just a heading change) in order to stay on the Great Circle?

If the Earth were a perfect sphere, would be able to fly/sail on a Great Circle without turning?

Is there vitamin b12 in grass?

So I have heard cows get there vitamin b12 from grass, and was wondering if its actually in grass or just a precursor?

How are European and North American fish related?

Posted: 17 Feb 2020 04:27 PM PST

Perch, Pike, Walleye/Zander etc. are found in both and yet they are so far apart. Do their ancestors really go all the way back to when the continents were all connected?

How can a person have ADHD AND Schizophrenia when they’re believed to have opposite ‘causes’?

Posted: 17 Feb 2020 02:28 PM PST

ADHD is believed to be caused by a lack of dopamine (and/or noradrenaline) in the brain. Schizophrenia is believed to be the excess production of dopamine, the opposite. So how can somebody have both? Could it be that those who have both produce an excess amount of dopamine, but not enough noradrenaline (another cause of adhd)?

Is there anything different/interesting about people who get adderall induced psychosis/schizophrenia?

Are people with violent or aggressive tendencies more or less at risk for suicide compared to those who are not violent/aggressive?

Posted: 17 Feb 2020 03:46 PM PST

If people with violent tendencies are considered to be mentally ill or have psychiatric problems, then I suppose that also would satisfy my question. As in, I'm aware schizophrenia can cause higher rates of both violence and suicide.

Obviously, nonviolent individuals can also be mentally unwell and be at risk for suicide. I'm just curious as to whether aggression could be linked to higher or lower rates of suicide.

Does the quality of gold impact its conductivity?

Posted: 17 Feb 2020 08:59 AM PST

This is for a DnD campaign, just to clarify. One character is attempting to con another into buying her low quality/low karot gold in exchange for his high quality because the low one will "be a better conductor" for electricity.

I was wondering if she's actually right in this?
