Explain micturition.

Action here basically asked us toe, explain what this quote means. So the quote basically states that owning a home is a keystone of wealth, both financial affluence and emotional security. So essentially this quote here, if we unpack it, it basically means that owning a house so owning a house here is going to be a sign of financial, um, security and wealth. In other words, so essentially it lessens theory. Worry of the homeowner without having to, for example, go for mortgages or any particular loans that the homeowner has to essentially pursuit if they didn't really own the home.

All right, we have a quote. Your That's basically saying that a lot of Americans are just not ready for retirement, and that's because a lot of them are living kind of paycheck to paycheck and considering the amount of they earn and saying, This is what I have to spend for the month And then if I add this up, I most like this by 12. It's what I have to spend for the year, and they're not saving from their paycheck. And when most Americans are not saving any money, they're not getting ready for retirement that when that way, when retirement rolls around, they can't retire because their savings are not enough for them to live by. So this hope, uh, this quote just is kind of highlighting that problem and how most Americans are not getting right for retirement in the way they need to

The problem asks us to find for uranium to 38 how much greater it is compared to uranium to 32 each, or isotopes of uranium that has a number of protons of 92. So just so we recall here when we see, um, this representation of atomic elements, we know that using a template here forgiven atomic Element X, its atomic number is listed as a as a superscript. The number of protons E is listed as a sub script. So write that down, Will, quick is the Tomic number Z is number, uh, protons. So for this case, when we see uranium to 38 we know that it has an atomic number of 238. Similarly, for uranium to 32 which has the same number of protons in its nucleus, it has an atomic number of 232 for this problem, asking us to find that ah percent difference in, um, the radius in terms with reference to the uranium to 32 we need the following formula that is, the radius of the nucleus of an atom is approximately 1.2 times 10 to the negative 15 meters and that ah, distance scales with the cube root of the atomic number. So we already figured out our atomic numbers above in this problem. So let's sketch out roughly what we need to do to do this calculation. We need to figure out the radius of uranium to 38 and, um, subtract from that the radius of uranium to 32. We need to divide by the radius of 2 32 Since it the question is asking us how much larger to 38 is in relation toe the radius of uranium to 32. It's asking for a percentage. So ultimately, when we end up with the fractional answer, we need to multiply that by 100. So before plugging things in, we can simplify things substantially. If we dio a let will bit of simplification, let's just call this the No, let's call this the, um, distant. Uh, yeah, we'll call this a scale factor as and we know that this s times Ah, to 38. Um, taking the cube root of that minus 2 32 taking the cube root of that. And then we're gonna divide all that difference by that same scale factor, which is 1.2 times 10 the negative 15th times that same to 32 to the 1/3. And again, all of this is gonna be multiplied by 100. So, looking at this, we see that this s cancels. That's why I didn't go to the trouble of writing it out. Also, we can divide the, um, second term, the numerator by itself, and end up with a one here and that makes plugging this into the calculators substantially, easy, easier as well. So let's right out. Simplified version of this. We will have 2 38 over 2 32 this whole fractional quantity. Then we can cubed, take put in the cube root, take a cube root of Rather. And then we said, We're dividing this of second term of the numerator by the denominator. That leaves us with a one here. And then we're gonna multiply everything by 100. Plug in this in, you will find a value of 0.85 five percent. So it's point, um 855% larger and radius. So percent change in our, um going from uranium to 32 to uranium to 38

This problem asks us to find how much larger in terms of a percentage is the radius of the nucleus of a uranium to 38. Adam, how much larger is it in comparison to the radius of a uranium to 32 Out, Um, justice A refresher. Here. You'll recall that when we see an atomic element listed in this format, the superscript is theater Tomic mass numbers simply mass number. The sub script is theater Tomic number and the atomic numbers specifically is the number of protons that are present in the nucleus. So from the information in the in the given information of this problem, we can surmise that uranium to 38 has a mass number of 238 uranium to 32 similarly has a mass number of 102 132. The Kruzel formula for this problem is that the radius of a nucleus scales. And here's the scale factor here in proportion to the atomic number to the cube root, the cube root of the atomic number. More precisely, so find a difference. I'm sorry to find a percent difference in, um Tomic uh nuclear Radi I We need to, um, right out a difference equation. And here I'm going to symbolize the radius of the uranium to 38 is our sub 2 38 for uranium to 32 our sub 2 32 again were asked to find the, um percent change with respect to the uranium to 32 nucleus. So we're going to be dividing by it since they want a percentage after we take that, um, difference, Um, normalized difference. That is, we will multiply it by 100. So plugging in or I'm not plugging him, but putting in the using the equation above I'm don't wanna have to write this out repeatedly, so I'm just gonna call. It s here. Um, the radius of uranium to 38 is proportional to its atomic number of to 38. Que brute. And we're going Teoh, subtract the cube root of the atomic number of uranium to 32. We're then gonna divide by the, um, s times the atomic number of uranium to I'm sorry, the mass number of uranium to 32 taking to the cube root and all of this times 100 This could be substantially simplified. If you can see one that this scale factor cancels out and secondly, that we can divide the denominator and the second term, the numerator equivalent can simplify this equation as the cube root of this fractional quantity of 2 30 a over to 32 again that was taken, the cube wrote and minus one times 100. If you plug these into your handy dandy calculator, you'll find an answer. A point 855 percent. And again, that was the, um percent change in the radius of a Urania of Iranian Adams. When going from ah uranium to 32 to uranium to 38 that's our answer.
