I have no cookie sheet..can I take a plate,cover it with tin foil,then place cookies on top,then put in oven?
Without knowing what the plate is made from, I wouldn't recommend it, but you can easily double over a couple of thicknesses of foil and just use that as your baking sheet. Good luck! (and go get a cookie sheet tomorrow ready for the next batch)!!
How do you stop a cat from clawing everything?
I have tried everything. I have 14 year old cat that has changed her behaviors all the sudden. Nothing in our house has changed and the other cat is fine. In addition to meowing constantly and peeing everywhere, she all the sudden is clawing everything, including our expensive leather bar stools, pool table, and pool table cover. I have set her up with clawing toys and boards. I have tried to file her nails and that was definitely not successful. I've also put sprays and aluminum down but she is not deterred. Either I may have to declaw her or I may have to get rid of her. Please help!
How can you make a ship from a 35cm by 35cm aluminum foil and hold around 120 pennies?
A penny has a mass of 2.5 g for pennies minted after 1980 so 120 have mass of 300 grams hmmm - coincidence that this is a nice even number? Assume the aluminum foil has negligible mass, so you have to create a volume greater that the amount of wate rthat will be displaced. Water has mass 1000 Kg/m^3 A meter is 100 cm so a m^3 is 100cm^3 or 1 cm^3 has mass of 1 g so the volume is 300 cm^3 Now, I set up the following equations: using a square bottom boat with width and length w and height of the sides as h w^2*h>=300 2*w+h=35 or 35*w^2-w^3-600>=0 In order to minimize the strain on the foil, I want to make w as small as possible. So I looked for a minima, or the smallest w that satisfies the equations. After some calculus and excel graphing, I found that , a boat with a base that is 5 by 5 cm square will have height of 15 cm and displace 375 g of water before sinking. This gives you some freeboard. It also means that you have good overlap at the corners to give the vessel strength. The last question is, will it hold the pennies? A penny has a diameter of 19.05 mm and a thickness of 1.5 mm If the boat bottom is modified to be 1.9*3 cm or 5.7 cm by 5.7 cm, then a layer of pennies that is 3X3 will fit in the bottom. That's 9 pennies per layer. That means you need 120/9, or 14 layers of pennies to reach 120 ( there are 13 layers of 9 with the 14th layer having 3) 14 pennies have a height of 14*0.15 cm =2.1 cm So back to my ship: The bottom is 5.7 cm ^2 which makes the sides 14.65 cm tall It will displace a maximum of 475 g, well over the 300 requred. When in the water, it will be 9.2 cm from the water surface to the keel j
Is there a QM level explanation for why aluminum foil does not heat up in the oven?
Nothing “QM” about it. Of course it heats up in the oven. However, aluminum has a low specific heat, and the foil is thin, so has only a small mass. That means that when you touch it, your hand absorbs heat from it and cools it off very fast.Take about a square foot piece of foil, and fold it over several times, pounding it flat with a hammer after every few folds. Do that until the pile is at least half an inch tall. Be sure to pound it until it’s as solid as you can get it. Heat that in the oven for a while and see if you still think foil doesn’t get hot.
How do you write a polynomial function of 3i, 2-i?
Here's what you do: you stick an x- in front of each of those (3i and 2-i). But what you have to remember is that those numbers are complex, which means their conjugates are also answers: -3i and 2+i. So, here's what you have: (x-3i)(x+3i)(x-(2-i))(x-(2+i)) Let's do the harder set first. x-(2-i) and its conjugate, x-(2+i). So what you do, is you distribute that negative sign through the parenthesis so you now have (x-2+i) and (x-2-i). Now, pretend that +/-i isn't there for jussst a second and solve (x-2)*(x-2). If you FOIL it out, you'll get x^2-4x+4. So, now let's look at those +/- i. So, i^2 = -1. That's just a rule, in case you haven't learned that yet. If you have -i^2, that's the same as saying +1. So you have x^2-4x+4+1. Add your like terms and let's move on. Now for the (x-3i)(x+3i). You can foil this out, or you can do a short cut. If you don't understand how to do these, we should FOIL it out so you get the entire meaning out of it. So! you'll have x^2+3ix-3ix-9i^2. So, x^2 is fine. Nothing you can do with that. Now, 3ix and -3ix cancel out, so they're completely gone. And -3i^2? Well, remember, i^2 is -1. And -i^2 is just 1. So that's like saying 3*1 (or, actually, -3*-1, but same thing). So now you have x^2+9. Okay. SO now you have to multiply your two expressions together. so (x^2+9)(x^2-4x+5) so: x^4 -4x^3 + 5x^2 +9x^2 -36x + 45. I just distributed the first expression into the second (that is, I multipled each term by each term. If you call the first x^2 one, the 9 two, the second x^2 three, the -4x four, and the 5 five, I multipled one by three, one by four, one by five. Then I multipled two by three, two by four, and two by five. Following me?) and added or subtracted based on the individual sign of the term. So now you add your like terms and you should get x^4 - 4x^3 +14x^2 - 36x +45. Hope that helped!
Can I put a stainless steel pan in the oven?
Yes you can.Stainless steel tends to be very tough. This type of cookware does not chip, rust or even stain, at least easily. Stainless is also dent and scratch resistant.

Why does aluminum foil reflect heat?
First of all lets clarify two basic facts:Aluminum foil always has two sides with different surface characteristics. One of the sides is shiny polished and the other is left matt (no post-treatment). The matt side has not been post-treated after manufacturing of aluminum foil in order to be suitable to come in touch with consumables (foods), so its used as the inside of the wrapping. The polished surface proposed use is to be the outside surface of the aluminum foil wrapping in order to reflect harmful radiation from reaching the wrapped consumable.A polished surface of any metal, including aluminum, reflects radiation of a certain spectrum (usually including IR and UV) and not heat in general.Heat is transferred to a mass in three ways, conduction, convection and radiation. Out of these three ways, aluminum foil polished surface stops (in a high percentage) the radiation only and not the conduction or convection. So even if a sandwich is wrapped in aluminum foil and put in a furnace it will be heated anyway. On the other hand if aluminum foil wrapped sandwich if left to the sun beams it will absorb much less energy, in form of heat, than is its left without wrapping.
Can I substitute peanuts for pie weights?
I wouldn't, and the simple reason is because of the oils in the peanuts that would soak into the crust when the peanuts get hot in the oven. Use dried beans or rice, or even dry pasta shells would work. However, if you have nothing else, then put a layer of foil or baking paper down on the crust, then put the peanuts down to prevent the oils from causing any issue with your crust, and it makes for easy removal.
If I cut open two helium balloons in my room, will I die? I only cut them open, but did not suck in all of the helium directly.
Uh, no.Not unless the helium balloons are the size of your room, and your room is incredibly well sealed on all openings.First of all, the moment you cut the balloon open, the helium will immediately do what helium does, and head upwards. That means it will almost instantly (probably less than 2–3 seconds) distribute itself in a thin layer across the ceiling of your room.So, unless you’re 8 feet tall and tend to walk with your nose pressed against the ceiling, you’re not going to breathe any helium in at all.Second, if you’re in a typical house, then your ceiling, your walls, even your windows, look like a screen door to helium. Helium is an incredibly tiny molecule and will pass through nearly anything. It even goes through solid aluminum. One of the exciting things about graphene is that it appears to be the first material that can actually, reliably, hold gaseous helium without leaking.Mylarized plastic will hold air for months, even years, but a mylar helium balloon goes flat within days. Rubber balloons are even worse, with most of the helium leaking out within hours.The drywall and paint that your typical house ceiling is made out of is nothing compared to that.So, within a few minutes, even that thin layer of helium near your ceiling will be gone, and heading up to the top of the atmosphere.Now, just for the sake of completeness, if you did have that incredibly well sealed room, and two half-room sized balloons, then, yes, you could effectively asphyxiate yourself by cutting them open. The interesting thing is you wouldn’t even notice, because helium doesn’t trigger the “gasp” response that a buildup of CO2 does. Your body won’t even realize it’s being deprived of oxygen until you pass out and succumb.Of course, you’ll be talking like Mickey Mouse while it happens.
