How many ways can you answer 11 true and false questions and how do you get it?
There are 11 true and false questions. How many different ways could it be ordered? and how? For example
1. True
2.False
3.False
... and so on. How many ways can you answer 11 true and false questions and how do you get it?
2^11 = 2048How many ways can you answer 11 true and false questions and how do you get it?
For each question there are two option, True or False. Assuming each is independent of the others, the number of possible combinations is 2X2X2X2X ... - or 2^11 for short. I'll let you figure out how much that actually is. (Hint: It's a lot.)

Optics True or False question?
True or False? Why?
A cloud casts a shadow on the ground. If you could measure the actual size of the cloud and the size of the shadow you would find the size of the shadow to be considerably larger than the size of the cloud, especially if the cloud is at a high altitude.Optics True or False question?
the correct answer is:
sort of:
If it's a very, very sunny day, and the cloud is illumunated by the sun overhead, then the shadow is every-so-slightly larger, but pretty much the same size.
It gets a bit bigger if the sun is at an angle.
If it's a day when light is dispersed by clouds above, the cloud will have a partial shadow that is much, much larger, but a total shadow that is small or nonexistant. I define a partial shadow as a spot of ground that gets some of the light, but not all. Full shadow, means all the overhead light is blocked.Optics True or False question?
The source of light is far away, so the rays can be assumed to be parallel. Now you have to consider temperature/density/humidity/size of the cloud/highth of the cloud/curvature of the earth/ /index of refraction of the atmosphere above and below the cloud. All things being negligible, should be the same size
True.
Point a lamp towards a wall. Place your hand in front of the lamp, and move it closer and further away from it. Notice the change in the size of the shadow.
(Imagine some lines between the light source, and your hand, and follow them each to the wall. It should become evident)
In the morning or evening or anytime in winter, sure it's possible due to the perspective, in the same way that it's easy for your shadow to be much taller than you. With the sun directly overhead, the difference would be minimal; the shadow area would technically be larger that the cloud's horizontal cross-sectional area, but I wouldn't say ';considerably';. The distance from the sun to the Earth is so much greater than the distance from the cloud to the ground that the sun's rays at opposite ends of the cloud are very close to parallel.
I'm not sure about considerably larger but it should be slightly larger. The closer an object is to a light source, the more light it blocks. Consider though that a cloud, even at a high altitude, is not much closer to the sun than the Earth's surface when you consider the total distance of the earth's surface to the sun. it would only be a tiny fraction of a percent closer to the sun than the surface.
I'd have to say False

Question about false positive pregnancy tests?
I took a hpt and got a negative. Over a week later I took another and got a positive result. Then, I went to the doctor and got a positive result. Is it possible to get a positive result at the doctors office and it really be a negative. I am worried that it is actually negative and the test was wrong. All answers are appreciated.Question about false positive pregnancy tests?
Ok.....I've mentioned this several times before and I am going to again....... make sure you get a blood test at the doctors office. That is the one and only sure-fire way to find out if you're pregnant. I've had a false negative AND a false positive at different times in my life, so I will never trust those home tests again.
To Jennifer M (and anyone else who doesn't believe in false positive tests)..... I did indeed have a false positive once and I did not and do not have a rare medical condition at all. I am considered normal to doctors.Question about false positive pregnancy tests?
there is a small chance of a false + but a much higher chance of false -
So Congrats!
The chance of 2 false +'s is like slim to none!
I think anything is possible. I always thought people were lying when they said they had a false positive pregnancy test, having had 3 children, until it happened to me. I took a pregnancy test a couple months ago and it was faintly positive, there were two in the box, so I took the next one first thing the next morning, it was definitely positive. I told my husband and a few hours later I started spotting, I thought no big deal it has happened in all my pregnancy's. The next day I started bleeding really bad so I went to the hospital and they checked me out and I sat there for hours crying about losing my baby, the doctor eventually came back and told me my blood test came back with 000 hormone levels. So I was never pregnant to begin with. I called the company that the test was from and I sent back the test and I'm getting my money back. It was a horrible experience. Anyways I think the only way to know for positive sure is to have the blood test done and if that says positive than your probably pregnant.
congrats, you're pregnant!!
No, it detects hcg in your urine. You probably got a negative before because you took the test when your hcg levels were low. Congratulations are most likely in order. Especially if the doctors did a blood test then you are definitly preganant. Blood test detect hcg in your blood. Good luck with your pregnancy.
I would have to agree with the other answers. congrats
False positive only happen with a rare medical condition and every single test comes back positive each time. With a normal person positive is positive, no questions asked. The reason you got a negative the first time was due to it being to early to test or you did the test wrong.
By the way a doctor can confirm a pregnancy by doing a physical exam where he looks at the cervix.
You can get a false negative, but not a false positive. If you had a positive result twice, then you are pregnant. Did they do blood work? If the blood test came back positive, there is no doubt that you are pregnant. These tests show the amount of HcG in your blood, or urine. If the hormone isn't present, or is small quantity, then you will get a negative result. Once your HcG has reached a certain level, it will always show positive. A blood test is more sensitive and will show smaller amounts then the urine tests, but most doctors now will take a positive HPT as accurate. That's even what we use in the office. They are now over 99% accurate.
More then likely, you either ovulated later then you thought, or the first time you took the test, the levels weren't high enough to show.
Also, a test won't show that hormone unless you are pregnant. It's the human growth hormone that is only present when you are pregnant. I think congradulations is in order!!!
If you don't feel pregnant, don't worry, a lot of women don't at first. Some don't have symptoms, other then a missed period to clue them in. Usually morning sickness doesn't start right away, and other then normal period symptoms (tender breasts, moodiness) there really is no way to tell. You won't be showing yet, and there is no movement you can feel, so it's hard for most women to believe they are pregnant. It's a normal reaction. Don't feel bad, or feel like you should have known. Most women don't.
Treat yourself like you are, start on the pregnancy diet. If you don't know what that is, get and read ';What to expect when you're expecting';. It's the pregnancy bible to us. Treat yourself like you are pregnant and stop any behaviors could effect pregnancy like drug use, smoking, drinking alcohol, or any other behaviors you feel are wrong, or could be a problem later. If you haven't made your first pre-natal apt, call and make it. Good medical care now could mean the difference in a good pregnancy or a bad one. Good luck and congrats!!!!
No such thing as a false positive. You are pregnant!
If the doctor's test came back positive...it is positive. Sometimes when you take the hpt your hormone levels aren't high enough, yet to be read. Most likely that is why that happened to you.
The SAME thing happened with me. I took it and was negative, then randomly took it a week later and it was positive, and so was my blood test. The first one just means that you were too early for the hpt to pick up your hCG horomones!!
Congrats!!!!

True or false question- horses are rarely born bad but there are horses that are born crazy.?
Horses (or any animal for that matter) are NEVER born 'bad' - people, events and circumstances make them that way.
For the second part, it depends what you mean by 'crazy' - horses (and other animals) can have mental problems as a result of birth defects, inbreeding etc. and this causes problems in the way that they are ';wired up'; if you will. This is a physical thing, horses aren't born crazy in the sense that they are just plain daft.
All have their own personalities, based on their nature, temprament, uprbinging and the circumstances and events that they have experienced. Some are highly strung, others laid back. It depends!True or false question- horses are rarely born bad but there are horses that are born crazy.?
may be trueTrue or false question- horses are rarely born bad but there are horses that are born crazy.?
YES THEY CAN this happens rarely but there are induvidual horses and animals with brain issues that go unnoticed. Tumors, underdevolptment, chemicals while pregnant, and even genetics can alter the shape and size of brain part and simulation or these parts. The thinking and reasoning part of the horse's brain is not as large as other parts such as those responsible for movement and hearing say. So if something does go wrong with shape, simluation, harmones, or tumors the horse can be 'crazy'. But we tend to think of 'crazy' more as a personality type. No horse's personality is 'crazy' rather it is hindered and limited due to his limitations due to his health. Think of that horse as disabled not 'crazy'. be awre that this happens far more in other animals than horses because genetics are aimed for a good personality with atheltic abilty. Meaning we unknowning encourage proper brain devolptment suitable to domestication. It is more common to have these 'disabled' animals in crosses whose brains are different. (arabs a general athletic suited breed with less focus on temperment is bred with a shire who's brain is far more designed for personality due to their need for submission and extreme size when bred together may have a great ir not so great. Both of the breeds brains are simulated and have more or less cells and electricity going to certain parts.) however purebreds that are bred by unskilled or born from parents with pre-disposed gentic defects in the brain that are unrecognized, and often though of as crazy or 'hot', the foal may inherit their brain function and distrubution of brain cells as this is ditermined by genetic and DNA.
in all horses can be 'crazy', but this is more referred to as a personality type. Rather the type of 'crazy' i believe you are talking about is due to brain health and disablity due to gentics, inherit, tumors, simulations, and natural brain make up. We do not do nearly enough studies on equine brains partially because of their size and the expense with the equitment involved as well as the wide array of breeds all with different brain and cell distrubution due to our domestication of them.

True or false: question about chemistry?
true or false:
1. All atoms of the same element are identical in mass.
2. An electron configuration tells exactly where the electrons are.
3. Atoms in the same group have similar properties.
4. Very little of the mass of an atom is in the nucleus.True or false: question about chemistry?
1. Clearly false. Isotopes of the same element have different masses.
2. False. Electron configuration tells the energy levels of the electron not the physical location.
3. For the most part this is true, like in group IA and the inert gases. But there is a high degree of variability with in the nitrogen family, for instance.
4. Clearly false. Almost all of the mass of the atom is located in the nucleus where the massive protons and neutrons are located.
Now that we've told you the answers to simple questions (which you should have picked up in class), I hope you will be able to do some thinking on your own.
============= Follow up ==============
Touche. Or perhaps it's not a very good on-line class if it leaves you with questions like this. I've never thought that on-line classes were as effective as face-to-face instruction. Perhaps this keyboard-to-keyboard instruction is a mild improvement.
What you may read on-line or in a textbook is not always as simple as when you get to ask questions of an instructor where you can ask follow-up questions and where the teacher can, too.
For instance, you must have had some uncertainty about these questions, otherwise they wouldn't have shown up here. Clearly being told ';true'; or ';false'; isn't as useful as actually understanding the chemistry behind the question. So what is it that you don't understand about these topics?True or false: question about chemistry?
1. False - there are isotopes of elements which have MORE or LESS neutrons than the element on the periodic table.
2. I don't really clearly understand this question. If you are talking about where the electrons physically are in an atom, then no it's false because it is impossible to tell EXACTLY where electrons are in any atom. But, if you are talking about the electrons relative to where they are in molecular orbits, then the answer to this question is TRUE.
3. True - elements sharing the same group have similar properties. Look at the halogens, alkali metals, alkaline earth metals, etc.
4. False - the protons and neutrons are located in the nucleus and they are the atoms with the most mass. The electrons have smaller masses than both neutrons and protons.

True or false question management?
A good way of gaining insight into our behavior is by asking for feedback from others.
i would say its true but i have a problem with ';asking';! why would you ask someone and not realize your own behavior?True or false question management?
True. You get more objective views of your behavior because people are less biased about you than you are yourself.True or false question management?
true, because some people can't see there flaws, plus you may be perceived differently then you think and perception is sometimes more important then the truth.
You may not be able to recognize personal flaws or behaviors that others find annoying.
