All credit cards are backed by a bank. Look at your credit card, it will say something like "Issued by XYZ bank" on the back somewhere. Banks have access to capital, both their own and capital reserves made available to them by the Fed system

So when you swipe your card, the bank transfers money from their accounts to the merchants accounts, then marks the debit on your account that you get when you get your statement.

They do, but not for the reason you're thinking. When their teeth wear down to much or get broken they can't get them fixed. If they can't eat enough food to maintain their health they will die. On the flip side sugar is relatively rare in nature, so they don't get cavities like we do. They can get them, but not like we would with our diets and no dental care. Pets that eat human food often have cavities just like us, not to mention all the other health problems that can cause.

The moon’s (or any object’s) gravity is directly proportional to its mass, so yes.

If the moon was a hollow paper mache sphere you wouldn’t get nearly as much tidal effect here on Earth.

The force between the two is G(m1 x m2)/r^2

The moon does exert tidal drag on the Earth, slowly sapping rotational energy and making days longer.

The much more massive Earth has done the same to the moon, dragging it so hard that it’s now permanently fixed with one side facing Earth.

they do but the thing is that animals that experience these sort of problems end up starving or die by sickness, so in effect their teeth last their whole life. :V

the other major difference is that their diets in the wild are majorly different than human diets, the main reason we need ot take care of our teeth asm uchas we do is because ourdiets evolved ot have way too much sugars, which while a major source of energy are also weffectively "toxic" to the existence of Teeth.

The Schwann cell is a separate cell in the periphery nervous system. In the CNS oligodendrocytes do the same job. These cells wrap part of their plasma membrane around the axon of the neuron to aid conduction and we call that part left there the myelin sheath. https://www.ncbi.nlm.nih.gov/books/NBK27954/

In criminal cases, the hung jury rate is 8% to 10%. In closed jury room discussions, some are willing to compromise, but jurors will often succumb to peer pressure and reach a unanimous verdict rather than risking a mistrial by not coming to a collective decision. There's an immense pressure on jurors to conform to the majority decision which places a reliance on the presumption that the other jurors know better than the individual. Sucks, but a reality.

Banks incentivize people with money to bank with them and then use that money to loan to others and make money on the interest.

Credit card companies make money by charging a fee to the business that accept their cards and they make money on interest when people don’t pay their balance in full each month

Maybe I should clarify my point then. Taylor series is the way pretty much every system (calculator, computer, cell phone, etc) computes a square root. You can look into the c stadard library and find the the sqrt funtion is implemented with a taylor series. This is because it is computationally efficient and provides a predictable level of accuracy. The estimation algorithm that every other person on this thread has mentioned is really only used by people wanting to do a manual computation, or as an exercise in an introductory computer science class.
